They woke me up early morning with 3 TOO MANY calls & hanging up. So I decided not to answer. On my phone I locked in the phone # as Contact name SPAM. Then have all their calls go straight to Voicemail...instead of ringing. No more ringing but I see they still calling.
So now I'll change my voicemail to require callers to speak their name, before a call can connect to me.
HA! Gotcha!! (646) 784-2566 is now my bltch.
