No idea who it is, but was getting a call @6:30PM. Seeing from all those people getting the call on the same day, I think it is safe to take it as a telemarketer call and it will be blocked.
I got a call in Spanish saying that they were the electric company and that they were installing a "smart meter" and this was their last attempt to contact me. And that they were going to raise my electric bill by 16% if I didn't talk to them. They make it seem alarming and try to scare people into a scam. I asked to be put on the no call list, well see if they do.
