Who called from 9712298761

Call every day several times. No message. Scam

Every time I pick up there is nobody at the other end.  After about 30 seconds the call is ended.  I called back the number and got a recording saying we could be removed from the call list by punching in our phone number and then verifying the number once the robot read it back to us.

I would like to know what company this is.  I'm so close to getting rid of our landline because of calls like this, which seem impossible to stop.

Repeated calls and when phone is answered, no one at the other end.

Irritant calling.

THEY JUST HANG UP. IT'S HAPPENED 2 OR
MORE TIMES. NO SALUTATIONS.  NOTHING.
