Anyway, I disputed some collection account on Equifax several months ago and they deleted it on Equifax and Experian. It is still on TU so I recently disputed it again. Last week the collector sent me a letter regarding the debt (after not contacting me for years). Today I got another letter from them telling me that failure to reply in 7 days will lead to additional collection activity. It says that they bought the debt from another collector, who had bought it from the original bank. Anyway, do you think it's time for me to send a cease & desist and prove it letter or remove it letter to them? Or should I ignore? I'm afraid if I ignore it'll show up on my reports again.
