This is a Collection Agent group that uses illegal methods of contact (depends on state) They call and when a person answers hangs up. They repeat this until you call in to them to find out what is going on. Then the machine you call in to does not identify, it just records the call and then sounds like someone dialing out. Law enforcement tracked them for me. This type of call is illegal in Ohio where I am located. When I finally talked to a human, it turned out they were after some person I had never heard of, and we have owned our number for close a year now. So illegal, activity and not accurate in the first place. Needs closed down.
