Who are these people?

Called looking for someone who does not live here and never has we only had our number treated my wife like a criminal when she told them that the person who they were looking for does not live here and said the cops were coming to our house when I called back to try to talk to their superior they at first acted like they never called but then started being a real jerk and said they had no suporvisors

theatened person told them if they didnt send money to them in 30 minutes they were going to jail in a few hours , i called them bak since im pretty versed in the law on debt collection matters & telemarketing procedures they kept hanging up on me

Called into our business and verbally attacked one of my co workers. The caller called my coworker a [***] and threatened her that he was sending police to our business. He was asking for a past employee and when my co worker told him she no longer worked for us, he made up several lies about speaking with the past employee last week. When we called him back asking for his supervisor - he told her there wasn't one and hung up on her. We called the company at 866-789-8808 and lodged a complaint. Not that it will help - but we tried!

NCO called the # and found out it is actually Matrix Telecom and the guys name is John..
