Who called from 4070001664

Keep getting called. I don't answer it in case it's a robocall.

Aggressive caller.  Does not leave message.  The number is strange too 000.
Ignore the 000 callers.

Keeps calling but never leaves a message.

I have had 7 calls from  407-000-1664  in 5 days... so tired of this.

The number calls me several times a day and 8am this morning I had a woman ask "is this Robert *****?" when I said yes she hung up. AT&T will do NOTHING about it. AT&T SUCKS.
