DO NOT BUY!!!
I got a really bad experience with this website. It was that bad that I don't want to receive any sort of cadeau cards anymore.
I had two of them: a workshop and a relaxing one. Regarding the workshop, I literally contacted more than 15 places that were of my interest. None of them would take the card (even some of them didn't know about its existence what it was really strange to me).
For the customer service you have to be lucky. Fortunately I came across a good employee that could change my card for another one but there was another employee that shouted at me on the phone saying that she couldn't help me, what is stupid because if no one is accepting the card they should always provide a solution.
If it was not enough, I had another disappointment with the Verwendag one. I lost the money because the card expired the same day in which I got the service. You can see until when the card would be expired but it leads to confusion. Watch out!!! The day that states as a last day is NOT included.
In summary, do not spend your money in this website. Is not worth it in money and time and there are a lot of restaurants/spas/workshop places that don't accept the card and don't even know about the website itself.
They are pure scam.
