I have send the validation letters to the CA's I plan on disputing with the CRA's once i get the green cards back from the CA's. Once i get the updated reports from the CRA's how will i know if the CA's did indeed show me as disputing these claims ? I have some notations on my report now that say "consumer disputes this account" or something like that. Also, how many validation letters should i send before the Estoppel one ? Basically, im looking for information on what documentation i should gather to strengthen my case if i need to sue down the road. Thanks as always!
