Hi LK - I was wondering, when you send out your dispute letters to the CRA (disputing 7+ items), do you send this return receipt requested or just use regular stamps? How about when you send out letters to the collection agencies for validations? I can see this whole process getting pretty expensive, especially when they verify the ones I dispute. I recently got back my first round of letters and only 1 entry was deleted.. however, all the address corrections occurred.
