I have disputed on all 3 cra's. One on Dec 12, (TU) Experian Dec 12 and Dec 18, Equifax. I received a letter from Equifax saying that didn't know who I was (although they updated 2 things from my online dispute) and I sent the stuff to them RRR on Dec 26. They picked it up today from the postoffice.
So how long before I should be hearing from them? (I know the holidays slow things down but how big a slowdown?)
