Same here - for the past few weeks we get 2-3 calls from this number a day. Never anyone on the line and never leave a VM. I call back and it is always busy. The number is unlisted too.
Did a reverse phone look up- found this:
(979) 217-0702
Type: Land Line
Provider: Level 3 Communications
Location: Wallis, TX
This number calls every day. There's never anyone on the line when I pick up and never any message -- even though there's blinkining light -- when I don't
The number called me every day multiple times for the past 3 weeks. Upon answering, there was only silence and a hang-up.
I finally picked up today and there was someone on the line from "Qwest". When I asked what office he was in, he said he was only a contract company for Qwest, but refused to identify himself further.
He said they know many people have called the number back and complained about their faulty auto-dialer. He said he would fix it. Yeah, right.
