They called today. I waited for a voice and heard nothing. The people hung up.

this person calls about student loans and other financial obligations that are phony/non-existent when call-back is attempted the recording states the number is "disconnected" STOP IT NOW!!!

They just called and farted.

I was just called by them and there's nothing but a loud buzzing sound coming from the phone.

The number has called before and hung up.

I would treat them as spam/telemarketer.

They called, it was flagged as potential fraud, checked here, blocked.
