Internet Speedway Ripp off Mesa, Arizona

Back in august I purchased the Google Payout System, that same day I called and cancelled it.  Some how they enrolled me into this other program that I did not know anything about called internet speedway.  I never used their product and quite frankly did not even know what it was.  I didn't even know that I was signed up with them until I got my credit card bill in december; they were billing me $69.95 a month for a service that I did not even know that I had.  I called to dispute the charges and they said they would cancel my account but would not refund me any of my money since I could not prove that I had cancelled their program.  Of course I could not prove that I had cancelled; I didn't even know I was in their program.  The manager Brenda Stines told me that she had the last word and that I was not getting my money back.  I asked to speak to her supervisor and she refused saying that the buck stops here.  These people know that what they are doing is wrong and I don't know how they can even sleep at night.
