They won't stop coming. The DNC list has nothing to do with these types of calls, go to the FCC web page and read about the different ways to stop these calls. the info. is easy to read, both informative & helpful. I have a link if you'd like that is really simplistic, takes no time to 'get it' which I found yesterday, produced by FCC (DNC for Dummies , not really) it's about Caller ID but it covers all of this junk call info.
This number called the office yesterday afternoon. Upon seeing the caller ID of "BETTER MERCHANT", I didn't bother answering as these calls are robocalls pitching some company's particular brand of credit card processing.
So far in 2017, we've received similar calls from the following numbers:

I get this call daily. If I answer to tell them to quit calling, there is no one there and my phone line is dead for approx 60 seconds.... I have called our local phone company and they offer no help
