US Reader Service telling me they are goin to put a wage attacthment on my husband.. Tampa, Florida

I recieved a phone call from US Reader Service claiming I would only have to pay 11.22 a month. Now all of a sudden I am told I have to pay 42.80 a month and that I owe over 900.00 to this company. I have told them many times i need to cancel because my husband got laid off but they refused.

Today my husband recieved the phone call and they proceeded to tell him that if we dont pay by November 27 that they are goin to put a wage attachment on him for 100.00 a month till this 900.00 is payed off. My husband also told them that i never signed anything and that they could not take money from his paycheck. They said that it was electronically signed, and because we are married he is goin to have to pay.

 I also tried to get on there web site but there really is no information there. I signed into the my subscription and found that now i somehow have more magazines that were ordered but neither i nor my husband ordered them.

So my question is how do we stop them from doing this wage attachment, and how do we stop them from calling and harrassing me?
