Depending on what state you live in you may do a couple of things. First though, if you signed the credit card application and gave your SS#, you may be liable. If you were just a signer on the card you may not liable. You can send them a cease and desist letter (certified with return signiture request). You could file chapter 7 if the debt is large (last resort). Or you could send a demand notice of a Reccession and Creation of a New Contract. The United States code is 15 USC 1681h. Plus, if you are just a signed user of the card you could also send them Form COL (Violation Warning, Denial of Rights Under Color of Law). U.S. Code for this is: 18 U.S.C.245; 42 U.S.C. 1983 This U.S. code is used whenever someone is telling you that the action they are taking is required by law when it is not. They can be held liable for this. And last but not least, you may want to consult with an attorney in your state since you may not have time to research these U.S. Codes. Hope this helps
