I had two very old medical collections that this CA would do a PFD for. Well this CA is in the same town I live in. So besides getting it in writing when I went down there, he actually showed me the computer screen with my information and the accounts and typed in a three letter code and said "that is it when our systems update to the CRA's they will be gone". Sure enough a few weeks later they were gone. Guess they send their information in at the end of the month.
I was just amazed of how much time some of us go through trying to get a negative removed, when in reality it takes them less than 30 seconds to remove them.
