Robocaller did not leave a message.

I'm on the DNC list and they are now on my blocked caller list.

These crooks do not abide by the DNC list, it is a joke folks.
Do not answer calls you do not recognize. Let it go to VM, and if its important someone will leave you a message.
Do not press anything to stop the calls, it just lets them know there is a idiot on the line, and they sell your phone number to their crooked friends.
Do not buy anything from telemarketers. If we did not, they would not continue hounding us with these calls.

caller id read Hornell NY
another site records name as Gigmembership

Had a missed call from this number.  Thinking it might be a customer, I called back - got a recording that was a lot of blah blah blah, but didn't identify the business name or type of business.

Very aggressive caller, said our small business just got platinum membership, but wouldn't say what for!  Wanted to transfer me to someone who would give more information and activate the membership.  "WHAT FOR?"  So rude and totally unprofessional.
