EZ-1-Rate First they took unauthorized charges out my account,then they they won't be giving back Carson City Nevada

First, I was contacted by cell phone(don't know how they got my number)and was offered a free gas voucher for only 1.95 one time charge.I gave my account # and I thought that was it.ten days later a charge of 49.90 was taken out of my account.I called and the person I spoke was with told there was nothing I could do about it ,because they were a member of the bbb(better business bureau).I fikled a complaint anyway with the bbb. now I'm waiting to hear from them.I don't know where else to turn to.
