Who called from 9783648561

Called my cell.  They let it ring 2 or 3 times, then hung up.

Called twice within a half hour.  I do not pick up for numbers I do not know. No message was left.

"This is an urgent public service announcement regarding your electricity bill."

Scam.

Called my cell, I did not answer because only my family knows my cell number and this was not one of the numbers that my phone recognizes.  After a few rings they hung up.
