first CRA dispute was online, and got me absolutely nowhere. second CRA dispute was snail mail crrr after i had talked to the OC and stupidly trusted them over the phone that they would have it deleted. third CRA dispute was again mailed (crrr) along with a letter i somehow got the OC to mail me stating the account was not mine. iow, I SENT PROOF! Now they send me this piece of crap letter telling me 'this item has been previously investigated'. WELL DUH. I know it has because the idiots wont fix it! i recently sent a written dispute to the OC (to add to my paper trail) even tho I now know i did this all backwards. I just got my green card back from that yesterday, and I was all ready to dispute w CRAs again. So what can i do at this point? If i dispute again, will their next letter to me be something about it being a frivolous request? should i just wait another 30 days? what should i bang my head against in the meantime? grrrr.
