Who called from 4153435596

I answered, even though I didn't recognize the number. I said "hello" twice and no one responded within a couple of seconds, so I hung up. I've now blocked the number.

One ring, dropped call.

Called two days in a row, no message left either time. Callerid says SF..quit wasting your time and mine..

Didn't recognize this number and looked it up while it was ringing. Saw prior 800 Notes and didn't pick up.

ID says: "4153435596".....  Call, say nothing, ignore the screener's warning, and you get blocked! All scammers and unknown, unspeaking callers get blocked forever! Good riddance!
