these are scam telemarketers

Same issue as everyone else.  My Number is on the do not call list but  does not  matter.  I get 3 to 5 telemarketer calls per week.  If you can ever trace them to the source  they are in violation of the telephone consumer protection act or TC PA     As a harmed consumer you are eligible to receive $1500 per call if you can ever find the source.    The rules around the TC PA have recently expanded the definition of a solicitation call  as of July 2016.   Even the callers who say this is not a solicitation are in violation

No, you are entitled to $500 per call, it is up the the judge to award treble damages.  The TCPA does not classify sales calls (telemarketing) nor is it the governing law.

Have received a phone call every evening for the last week, between 5 & 9 pm; hang up when answering machine picks up.  You'd think they would figure out I'm not going to answer by now!

Caller hung up as soon as I answered my cell phone on this number. They are checking for later use for scammers I suppose.
