National Readers Service Can't cancel my account NRS Scam Pittsburgh, Pennsylvania

The company called me sometime back now saying if I wanted to subscribe and unfortunetly unknowning i did. They said it would be $68.28 for the next 19 months. They asked me to give them my CC#, which i have cancelled and now they sent me a bill that I owe and when I called them about it they told me I had owed the over one thousand dollars, and also my SSN. I've done my research and found out that the address i was given is fake. I also looked it up on the internet for other responses and they were all pretty much the same as me. I tried calling the suppose number of National Reader Service Costumer Service and they say that i got the wrong company. I need to cancel my account now!
