He called a 12 year old and asked him to get a loan. He was told not to call anymore or we were going to call the police. He said he will call tomorrow. I kept telling him I will call the police and he said he will call in a half hour. Extremely argumentative!
Your callers are criminal, and have no regard for the law. They are most likely calling from a spoofed number. If the phone is a smart phone, get a call blocking app, many are without cost.
