They are soliciting for mortgage rates with no opt-out selection.  I punched through and told them I was recording the call and wanted the name of the company they were calling from - they hung up.

I got a call from it yesterday and today; both times it disconnected the moment I answered.

called me didn't answer no clue

Calls and hangs up as soon as I answer at my business. Called back and says the number is disconnected.

This number called yesterday and today.  Yesterday I answered and was immediately disconnected, today I did not answer, they left no message.  Caller ID is fake, recording says number is disconnected.
