Caller ID says MCCA
They don't leave a message just hang up but keep calling. I can't find out who they are.

A call came from the same number last Thursday and they just hang up  and don't leave a message. I'm housebound on an oxygen machine and it's hard for me to get to the phone so this is very annoying and my number is unlisted, they keep calling

They are a collection agency based in Hartford CT. They called me regarding my $48.00 co pay I owe Backus Hospital in Norwich.
