一元到四百元的利息也太高了，不可能。如果是真的一元到四百元，後麵應該有別的主線故事。討債公司是不能另加費用的，你這個說法讓討債公司蒙受“不白之冤”。
下麵是對討債公司的約束：
15 USC § 1692F - UNFAIR PRACTICES
(1) The collection of any amount (including any interest, fee, charge, or expense incidental to the principal obligation) unless such amount is expressly authorized by the agreement creating the debt or permitted by law.
(5) Causing charges to be made to any person for communications by concealment of the true purpose of the communication. Such charges include, but are not limited to, collect telephone calls and telegram fees.
