Are there any pros and cons to disputing the same creditor to the all CRA's at the same time? I have a lot of work to do to correct my situation and I want to make sure I'm on the right track. Any comments?
That would be costly considering to do it right you need to send CRRR. I would first try Credit Bureaus, if you get lucky you won't have to deal with most of the collection companies or creditors.
