Noone on the other end when i answered

three calls today with no one on the other end of the call.

This number called my phone on Christmas eve, who are you?

This is a computer calling - if you stay on the line, a real person comes on.  I assume it's some kind of debt collector - they ask for owner or AP and won't give me any info because of privacy laws (ha ha, if I said I was AP they would tell me). Anyway, they call here a lot so when I see the number, I just put it on hold right away and leave it there so when the real person comes on, then THEY sit on hold and don't know what's going on. I just chuckle.

I received call at work.. several times... returned call... they didn't know what they called me for ????
Left #888-303-8773, so I called since I assumed it would be important since I was called during work.
Yes collection account for account already paid... I asked why are you calling me at work....... they said they would delete that number ????
