Some schmuck named 'Marcus' claiming to be from 'NRG'... I knew it was a scam, and let him drone on until I disconnected him right in the middle of one of his blabbering conversation sentences.
Caller ID said "unknown caller" so I didn't pick up this scam call. Like a previous posting, I've often thought of giving all bogus info (fake names, bank name, credit card #) and let them waste their time going crazy trying to use it.
Live person calling for "Mr or Mrs ____". Said he was calling from NRG, apparently in an attempt to solicit for their services. Caller ID read UNKNOWN NAME.
Reported the DNC violation. https://complaints.donotcall.gov/complaint/complaintcheck.aspx
