called yesterday and again today....caller ID said ..unknown name and they left no message.

Caller ID "UNKNOWN NAME", calls often, leaves no message.

Also uses 770-854-0037 .  It traces back to Roopville, GA.  They call two to three times a day.

The first call was on a Sunday afternoon.   I work nights and can hardly deal with derps.

I called the number back and got a recorded msg: "U have been called for marketing research or a sales call."  Sadly that probably opened me up to further repeated calls.

770-854-0199 is located in Roopville, Georgia.
Its exchange 854 is managed by BELLSOUTH TELECOMM INC - GA.

I'm getting really tired of these calls. They also come from 0037. No one responded when I first answered the calls from either number. So now, I just don't answer at all. I get several calls per day. :(

Called Sunday evening at 6:23 PM.  This puts them lower than low by calling on a Sunday.  Not even political calls call on Sunday.  Whoever runs this scam is the worst of the worst.
