Have been called nearly 15 times by Credence Resource Management ( phone : XXXX ) with no attempt to leave a voicemail. I returned call and asked who they were, and they said they were not allowed to tell me without me giving me them my name and information first. I said that was not true and they were required to tell me if this was a chance to collect a debt or even simply what their business did before I gave them personal information. He kept saying " I will not. I will not. '' I said my stepfather works for a debt collection agency and I interned there so I know the rules and ethics. He said, " good for you, but I 'm not saying anything until you give me your name and address. '' Completely rude, unethical, illegal, and harassing as they have called nonstop without voicemail ( even a simple voicemail just disclosing a number and to call back )
