When I answered the phone, a robotic female voice said "Goodbye" and hung up.  Probably a robocaller searching for active phone numbers.

HOME IMPROVEMENT JERKS, THIS # HAS CALLED ME 20 TIMES, CALLED # AND EXCHANGE SAYS "DISCONNECTED", WENT TO VERIZONS' WEBSITE TO BLOCK NUMBER... IF ANYONE HAS INFO ON THESE CREEPS, PLS POST... THX!

I've seen the number on my caller ID but have never picked it up because I didn't recognize the number. Today, for some reason, I picked up the phone. Some guy said my last name wrong, (which is always a red flag) and I asked who was calling, and the jerk hung up. Thanks for letting me know it's a stupid home improvement cold call. Will not be answering from here on out.

Spouse hung up on them.

Called, said it was a market call. I asked what it was referring to. Wouldn't tell me. Waste of time!
