Yeah these people are [***] (trying not to sound too mean and watching my language). Calling at 7am through to 10pm, and now on weekends.
I did answer them once and found out I was in collections with a bank that I closed the account about 6 years ago. Not sure if this is a scam since the account was closed, but either the bank or these people are going to have to deal with a very angry man in a couple weeks.
...and they are the collection agents that people have mentioned.
This caller has been calling several times a day. They ask for my adult son who hasn't lived in my household for 2 years and has never lived at this address. This a debt collector. When I pressed 3 he asked what I could do for you. When I told him he called me he said oh he came in on the automated line. He then stated that I had to give him his phone number, address and employer. When I told him he doesn't live here that should have been the end of it according to the goverment website.
