Who called from 4017924545

Caller ID said Schneider Electric; answered because I do business with them but they didn't say anything.  Could have been a spoofed number

I called this number back, and the recording purported to be customer service for some electric company.  It's gotta be a telemarketer.

this number called my direct office number but did not leave message

This is APC

someone keeps calling my cell but no response if I answer.  Nothing if I call back.  Scam???
