This site actually exists, I just checked it.
The site is hosted in Germany and therefore is subject to the strict German law in this respect.
I have a very reliable friend in Germany, and I therefore can offer you some free, basic assistance in reclaiming your money in case you chose to take legal action against them. If you agree, you will be asked to supply some more detailed information and expected to do so. Basically, there are some good chances to get your money back if your complaint is well-founded and if sufficient evidence can be given.
Please also note that we can offer this free service to you only in case you do not live in Germany yourself. If you live in Germany yourself, you have to take care of the matter yourself.
Contact me by email if you need assistance in this.
