I have heard that disputing things so close to fall-off date can actually prolong their existence on your reports, as they're investigated.
Isn't CRTP set from DOFD, which would have to be at least 30 days from DOLP...so I see if your last pmt was 11/1, then DOFD would have been 30 days *after* that 11/1 pmt, making it 12/01, as the CRA has listed.
You would need to call Efax directly to find out the actual, factual DOFD they have listed. THey can't choose to go by DOLA -- rules say it's DOFD that governs the 7-yr CRTP, they don't get a choice. Now, they can choose which date they actually put for your viewing pleasure on your CRs, but that doesn't mean that's their calculation date. Give them a call & ask, then go from there.
