Just to chime in on Experian, I hate them. I've found the others much easier to deal with. Equifax was initially difficult but gradually became easier. TU always seems the most customer friendly.
Well, EX finally deleted and I updated my reports to find out that TU reinserted. They haven't sent me the 5 day notice. I am going to give it a couple of days, and then I will sent them a letter.
