keep getting these calls, name unavailable.  Won't leave a message, keeps on calling

I have received a call today. And I get them on my wireless and landline one after another. The number changes daily.

I get these calls almost daily too. All from the 412 area, different number each time too. Very annoying. I never pick them up, they don't leave a message.

JUST got a call from this number.  These calls are scam calls.  This is the 9TH different number I've gotten from this group and the 12th call about the spiel for changing electric providers.  The prefix "177" comes up as invalid so the number can't be traced.  And except for a call from an 866 toll free area code, they are all the 412 area code.

I will be reporting this to DNC and also to the PA Attorney General's office.  Anyone else getting this should also let Harrisburg know, too.

Annoying
