I have just received a phone call from a collection agency stating that they had purchased an alleged old debt from SBC from 1998. I don't know how they got my cell number and they would not tell me. I dispute this old bill especially when SBC called Ameritech then could not produce any old bills. What would be the staute of limitations on this old original debt from 1998 and does it change because a collection agency purchases this so called debt?

Also, would my current cellular company have given out my number?

SOL depends on the state that you're in. Where were you living in '98 and where are you living now?

Your current cell provider should not have given out your information under any circumstances.
