"Missed Calls" on phone showed "BARDWELL TX" with phone number 1-469-300-4205. We NEVER answer our phone if we don't recognize name or number! Legitimate callers will leave message for us to return call; all others, SOL!!!
This one apparently bypassed Robo and got to me as 11 469 300 4205 with an indication of "invalid number". I thought I would have some fun and answered very slowly and in a deep voice "Hel-lo" when he said "Hello", I said again "Hel-lo"; he said "mr. xxxx?", I said "Hel-lo"; He said "Mr. xxx, can you hear me?"; I said "Hel-lo". He hung up.
