That is my question. I sent out DV letter to NCO on 4/24....Green card says they signed on 4/28. I was just about to send out estoppel when I noticed that is has been deleted from Experian only! And this comes only a few days after Experian had sent my dispute results and said that NCO "remains". I am not sure I should send out the estoppel if the deletion process has already started.....Heading on vacation for a week and thought I might just wait until I get back and see if it has been deleted from all three. Any opinions? Thanks.
