Owen Buys a Restored 1969 Dodge Charger from Prime Restorations

Essay

Owen buys a restored 1969 Dodge Charger from Prime Restorations Inc. on credit but makes no payments on the account. Quentin, the owner of Prime Restorations, calls Owen at home on a Monday morning at three A.M. Quentin represents himself as RiteNow Collection Agency and demands payment "or else." The next day, Quentin sends Owen notice that he has thirty days to request verification of the debt, during which its payment will be suspended, but that if he does not pay the full amount due within five business days, Quentin will arrange for the "destruction of Owen's good credit rating." Which laws has Quentin violated, if any, and in what ways?
