I recieved a letter from a CA for a debt that is at lease 5 years old.(SOL in IL is 5 years). I was going to send the DV letter, but I'm afraid that any communication with the CA will result in it showing up on the CR. They are showing up in the Inquiries section of the CR (2X in last year), but no where else. Should I go ahead and send the DV letter, or what would happen if I just ignore it? can it be put back on the CR?
