Who called from 9518241321

Called. No message. Blocking number.

Called I answered, asked me about my electric bill. I said, bad time and blocked. My number is unlisted, how are they getting it? Next time they call, I am going to turn it around on them. See how they like it.

Called in today lunch time, did not answer. Don't answer calls you don't know, If it is important they will leave you a message.

Nuisance calls daily

This number seems to be from a company that provides solar energy installation as they asked how much my electric bill is; I responded "I don't need any help".  Will not answer in the future.  I am on the National DNC Registry.......how are they getting my number????
