I picked up and heard a lot of voices (like it was a call center of some sort).  I said hello and no one responded so I hung up.

Answered so I could tell them exactly what I thought of them. They must have read my mind as they hung up immediately. Could have been a computer phishing for working numbers. Won't do them any good since the number will no longer work for them. Blocked them.

This number called twice,  close together,  nothing on the other end.

Called right as we were sitting down for Mother's Day supper!!
Did not leave a message.
Bye. Bye whomever you are--- You are now BLOCKED!!!!
