First, the original debt was under a different last name. It's already been deleted and re-inserted on my Equifax CR. Should I type the name under which they have the debt or should I type the one I'm using now. Second, the original debt was listed under a different address. Should I use THAT address on the letter or my current address. Okay...I have 3 questions. The 3rd being, since my name and address have changed, should I just attack Colletech with a validation letter? If I do so, wouldn't I be giving them my NEW information so they can bug me, IF they validate?
