Caller is one of the Pennsylvania Electricity Suppliers (I didn't catch the company name). But, VERY PUSHY pitch: "If you'll get a pen and your last electric bill, I'll apply a lower rate to your next electric bill RIGHT NOW!" without stating what that rate would be.
On June 13, I got a call from 267-428-1572, concerning my electric bill. I did not allow him to finish his call, as I thought it was a scammer. So, I hung up on him.
