I have a collection agency trying to collect $427 on an original amount of $377. The original debtor is a cable company. Is it lawful for a debt collector to add interest to this type of debt and ask for more that the original amount? If I am reading correctly [15 USC 1692e] § 807(2)(a)says no as does FDCPA. [15 USC 1692f] § 808(1)
