Who called from 5123542709

I picked up and ONLY LISTENED, as I did not recognize #.  I waited for about 7 seconds to see if they might initiate "hello, anyone there?", but they just hung up. They are probably phishing to see if someone picks up (with voice) so they can pass my #  around for marketing or scams.  Try this new way of answering, waiting for them to speak first!

It’s the Survey SCAM. Call back gets, "Thanks for calling.  The survey you were called for is now finished."  This robo "survey" is how the telemaggots get around the DNC regulations.  There is no survey just some nonsense questions.  You'll be offered a free something for completing the survey then asked for you credit card number.  It's a SCAM.  Block it.

No Caller ID, no message

They called my cell, and started to tell how iʻve won some holiday package. Before asking my name or telling what fictional package. Bye!

Todd from GE Home Security... can you hear me OK?
Or so the computer voice says so.
