I sent a Cease and Desist letter to a confirmed scam collection agency. The letter was sent via certified mail. I received confirmation that the agency picked up the letter and signed for it on 8/3/2012. Today, 8/10/2012 I received another call from this same 'firm' at my place of business. They don't speak...they just call and I hear dead air. I know its the same scam company because their phone number shows up on my caller ID at work. How do I get this to stop? I've already reported them to the Attorney General's office AND the FTC. Now what? I'm from Pennsylvania.
