Also, pay attention to this recent case. While Fair Debt Collection does not, at present, apply to collecting a creditor's own debt (which would include a bank collecting its own loans), banks are expected to be "above the fray" and not act abusively.
In this recent FTC action against an auto lender that also collects third party debt, the FTC charged them with FDCPA violations on debts for third parties and UDAP on debts collected on the firms own behalf.
