www.yourmailinglistprovider.com Scam

am a victim of apparent scam website in Belgium. I have registered account at this website http://www.yourmailinglistprovider.com/. They have charged me $100 for a period of two months for mailing service they did not provide. On the website they offer email services... I have tried to use their service but they simply do not provide it.

I have tried to contact them over the email several times as well as over the phone, apparently it seems like a scam as nobody replies. Eventually thay just simple closed my account without any email.

What are the steps I can take to recover the money they have charged me? Also I think other people should be warned about this scam.

What government run offices in Belgium can I contact regarding this scam?
