Even if you send the CRA full documentation, supporting your dispute, the employee who is investigating your dispute, reduces your letter, documentation, etc., to a 2 digit code, which then gets sent to the furnisher(OC), not the documentation, just the code. The furnisher(OC) never even sees the documentation supporting your dispute, only the 2 digit code. The CRA's do not convey the full dispute or forward any documents to the furnisher, which as a result, nearly all consumer disputes are verified against the consumer. Dispute, dispute, dispute, and MOV if necessary.
