I was a security guard And was taught the importance of not impersonating a police men. But we also could not even let people "assume" we were cops. Even letting them assume is a crime that will cost anyone years in jail....
If you want to get collections to stop calling you say your not that person and have you removed from there
system it works every time don't call them back you need to pick up the phone when they call each time the calls will stop.
