I'm actually dealing with Portfolio right now as well, and also with an old Providian, small world huh? I tried on a couple of occasions to get a PFD, but was unsuccesfull with them, they told me that it would be a breach of contract with the CRA. Also I wasn't in any bargaining postion either since I didn't have the full amount upfront to play hardball with. Anyway besides that I thought they were very professional and understanding, I didn't have the full amount of what they wanted for a down payment, 20% of the balance due, but they let me spread it out over a couple of pay periods.
Definitly try theymight.
