Who called from 3122790165

I get this call every couple of days lately.  They never leave a message.

I just got the call from this number too, i answered, and they just hung up....

I get 4 to 5 calls a day from this number every day,its very annoying they hang up every time and they never leave a message.whats up ??

This is getting annoying!  Several calls a day from this number - it rings then hangs up.  I won't answer it, but I wish I could stop it!

Received 7 calls in the past 5 days from this number. Never leaves a message. I called it back and got an automated voice saying "Please hold for the next available agent." No company name or anything. Quickly was connected to someone who said "Hello, may I speak to Jamie?" (I am not Jamie) Could be a collections agency? Going straight to voicemail from now on.
