Who called from 7277484797

They call my business line. Sit there in silence and won't say a thing. Then finally hang up on me. Going on my little block box!

This is a scammer who ignored the DNC list.  It was a Robo call selling "Obamacare" health insurance.  Caller ID: "SERVICE DEPT".

I see from other posts that this is about time shares. I don't have one so why are they calling me? Is there any way to stop junk calls all day long?

727-748-4797 called Jan 23, 2015 at 12:39 pm.  Caller ID = Service Dept (sounds like a scam to me).
No Message.  Lots of reports on 800notes (thank you).
BLOCKED

Called this morning, left no message.  Caller ID said  Service Dept.

I feel like putting a message  on my phone:

No Name, no number, no message,  no answer
