Who called from 3123405567

Left no message. then called and hour later with a different number

SCAM about lower electric utility rates. Returning call gives no information about who is calling.  I think the company might be called SCAM Electric.  I have lost count of all the electric utility phone calls from Area Code: 312, Exchange: 340, numbers range from 5544 to 5588.  This is a range with 44 different numbers.  I wish there was a way to block Area Codes and/or Exchanges.  Any ideas?

Have received these calls for months

Have blocked 312-340-5545,5548,5567,5580,5582..they just swap the last two digits

Filed a DNCR complaint twice

guess they're still working on it

These people keep calling.  So annoying

I received a call from 312-340-5567 at 6PM CST. I always screen calls that I don't know. They left no message.
