Who called from 4803768643

I didn't answer.  Left robo-message regarding lowering my electric bill.  (I don't even live in Arizona anymore but get swamped with spam calls from Phoenix and Sierra Vista these days.)

I answered and kept saying hello nobody would answer and then after about 15 or 20 seconds the call hung up... It's either telemarketer... or scammers

this number called at 1:40pm and left no message; upon c/b  the only statement was, press 9 if you wish to be put on the do not call list.  so I did

calling and not answering

Called my cell phone, no message was left. Will block the number.
