The FDCPA mandates that debt collectors can’t call you after 9:00 p.m. or before 8:00 a.m. unless you tell them that they can.
Debt collectors have the right to try to collect on the debt that you owe. However, they don’t have the right to harass you into repayment.
The FDCPA restricts this activity and mandates that a debt collector can’t call you at work if you’re not allowed to receive calls there.
