I found this site and it's been helpful, but I have a question. I got a call from a CA, (and haven't called them back because I wanted to ask some questions here first)and I think I know what they are calling about, and it's about a debt that goes back to 1992 or 93. Now here's my question: How should I deal with the CA, should I ask for a date on last payment and say the the debt is to old and stop calling or ask for a validation letter and reply ? Any info and suggestion are greatly appreciated.
