How can I withdraw?
You must inform the seller of your withdrawal. You are on the safer side if you do this by sending an email and the seller confirms the withdrawal. Or if you send the withdrawal notification by registered mail. In this way you can prove that the seller has received your withdrawal notification.
What are the consequences of withdrawal?
The withdrawal renders the contract invalid and you are no longer bound by the contract. The seller must refund your money and you must return the goods. The seller does not have to return the money to you until he or she has received the goods back from you or you can prove that you have sent them.
