The consumer’s right to withdraw from the contract

The consumer (the above applies exclusively to natural persons who acquire the article for purposes outside of their commercial activity) has the right to notify the seller within 14 days of taking over the articles that he withdraws from the contract without having to give a reason for his decision. The deadline starts counting one day after the date of collection of the items.

Withdrawal from the contract is sent by the consumer to the seller’s e-mail address: [email protected]

The seller sends him the Form for withdrawing from the contract to his e-mail address.

In case of withdrawal from the contract, the consumer returns the received item by post to the address of the company’s warehouse: Centrum cognitio d.o.o., Šarhova ulica 34, 2000 Maribor, Slovenia or brings it to the address in person.

The return of the received items to the company within the withdrawal period is considered a notice of withdrawal from the contract.

The consumer must return the item to the seller undamaged and in the same quantity, unless the item is destroyed, damaged, lost or its quantity has decreased through no fault of the consumer. The consumer may not use the articles unhindered until the withdrawal from the contract. The consumer may inspect and test the items to the extent necessary to determine the actual condition. The consumer is responsible for a decrease in the value of the goods if the decrease is the result of conduct that is not absolutely necessary to determine the nature, properties and functioning of the goods.

The only cost charged to the consumer in connection with withdrawal from the contract is the cost of returning the items (which, in the case of shipping, is calculated according to the price list of the delivery service and depends on whether it is a shipment/package/cargo). The item must be returned to the seller no later than 30 days after the notification of withdrawal from the contract (purchase) was sent.

The consumer does not have the right to withdraw from the contract for contracts, the subject of which is an article that was manufactured according to the consumer’s precise instructions, that was adapted to his personal needs, that due to its nature is not suitable for return, that is perishable or that has already expired best before. There is no possibility of withdrawing from the contract if the consumer has in any way reduced the value of the device by using or damaging it or by an action that affects the integrity of the product.

Withdrawal from the contract is not possible for goods:

  • for goods or services, the price of which depends on fluctuations in the markets, over which the company has no influence and which may occur during the withdrawal period from the contract;
  • for goods that are manufactured according to the exact instructions of the consumer and adapted to his personal needs;
  • sealed goods that are not suitable for return due to health protection or hygiene reasons, if the consumer has opened the seal after delivery; (e.g. serums, creams and cleansing mousse)
  • goods which, due to their nature, are inseparably mixed with other objects;

The refund of payments made, including delivery costs (except for additional costs due to the choice of a type of delivery that is not the most affordable standard form of delivery offered by the company) will be made as soon as possible, but no later than within 14 days of receiving the notice of withdrawal from the contract . The company returns the received payments to the consumer using the same means of payment that the consumer used (which is most commonly by payment to a transaction account), unless the consumer has explicitly requested the use of a different means of payment and the consumer does not bear any costs as a result.

In case of withdrawal from the contract where a bonus, discount code or promotional code was used, these funds are considered as a discount and are not returned to the user. Only the paid amount is returned to the user. When withdrawing from the contract, the gift voucher is considered as a means of payment and is returned to the user as a gift voucher, and the amount paid is returned to the user.

In exceptional cases, when the items are not returned in accordance with the ZVPot, we can offer the consumer the purchase of the item with appropriate compensation, which is determined in the minutes upon return. The purchase with a reduced value is taken into account upon confirmation of the consumer by e-mail. The consumer benefits from the aforementioned redemption fee only when ordering another item of the same or higher value.

The right to a refund in the case of warranty claims and material defects is more precisely regulated by the provisions of the Consumer Protection Act (unofficial consolidated text).

Withdrawal by the consumer from the contract for items in the set

If the consumer decides to withdraw from the contract for the items that make up the set, he can request an exchange for the same set or a refund for the entire set. The consumer can exchange the item from the set in the event of a material defect or damage to the item, but cannot request a refund for it. In case of claiming the warranty of the item from the set, the manufacturer’s warranty period applies.

Returning items

More important instructions for returning items:

  • When you return the items to the seller (Centrum cognitio d.o.o.), you must attach a contract withdrawal form. Also attach a copy of the invoice.
  • You can return the items in person at the pick-up points or send them to the seller’s address, Centrum cognitio d.o.o., Šarhova ulica 34, 2000 Maribor, Slovenia.
  • We recommend that you use a delivery service that allows you to track the shipment and that you properly prepare the items for transport (you can use the original packaging or other suitable safe packaging).
  • Shipping costs are always covered by the sender, unless otherwise agreed in advance. We do not accept ransom payments.
  • In the case of returning the item, the buyer must properly protect the item before handing it over to the carrier. The item must be protected by the original packaging or packaging that can protect the item in the same way as the original packaging.

The funds you have in your Tina assistant account can only be used in full in one lump sum.

In case of withdrawal from the contract where a bonus, discount code or promotional code was used, these funds are considered as a discount and are not returned to the user. Only the paid amount will be returned to the user’s TRR or other means of payment, insofar as the user expressly requests this. When withdrawing from the contract, the gift voucher is considered as a means of payment and the amount is also returned to the user.

The obtained prize cannot be paid out or returned to the Tina assistant account under any circumstances.

Treatment of damaged shipments (compensation)

If, upon receiving the shipment, you noticed that the item or shipment is physically damaged, its contents are missing, or it shows signs of being opened, you can file a compensation procedure with the Post Office of Slovenia. You do this by bringing the shipment (packaging + contents) to the post office as soon as you notice the damage or looted shipment, no later than within 30 days of receiving the shipment. Please note at the post office that it is necessary to fill out the Record of Damaged Shipment, which you must also sign. After receiving all the necessary documentation, a claim for compensation is submitted to Pošta Slovenije. The request at Pošta Slovenije is processed by a commission and based on the answer or approval, the purchase price is refunded or a new item is ordered. Together with Pošta Slovenije, we will ensure that the compensation is resolved in the shortest possible time.

If the package was delivered to you by GLS and you find that the item or physical shipment is damaged, missing contents, or shows signs of being opened, you can file a claim for compensation. Damage must be reported within 7 calendar days from the date of receipt of the package to the e-mail address [email protected]. When reporting damage, we will also need photos of the package, (inner) packaging, damaged item, DHL label and a description of the damage.
