Same here. I keep a spreadsheet of scammers calling me. Easy to tell from the number that it is a scam so I pick up the phone and say nothing - just silence. See how they like it. Usually the don't call back.

Robo-call from oily, ultra-cheerful, totally phony sounding female voice
SHE: Hi, this is Nicole from Senior Benefits, how are you today?
ME: (in sarcastically sweet voice) Oh I'm just fine.... Nicole.
CLICK.

I get a lot of these, but this is a new one for me. I can just imagine what benefits they are offering. Maybe a free tote bag to carry my free medic alert pendant, back and knee brace while I go on my free cruise while those nice folks clean my air ducts, carpeting and install my low cost, energy-saving solar system.

Second call in two days--first time we didn't answer.  This time there was no one there.  [***]

We're on the DNC list.  Should NOT be receiving random sales calls.  Let this number slide before, but checked back here and recognized the same posts, so they've called us more than once.  This time, they're blocked.  Go ahead and block 'em now, they will keep calling.

Called, I did not answer.  Caller left no message.  Probably Telemarketing SCAM
