This is the latest of many fake numbers used by frequent solar telemarketer pests A1 Solar. Block the number, they'll have a new one soon, block that one too.
I've received dozens of calls from solar companies in the past month, along with all sorts of anonymous calls from numbers that many other people have complained about on 800notes. Even though my number has been registered on the Do Not Call list for years, the calls keep coming. I've even gone to the trouble and expense of having my number unpublished, but it hasn't helped!
So here is my new solution - My phone service provider has an option to have specific calls forwarded to a phone number of my choosing. I have listed 20 phone numbers from scammers and telemarketers that are now all being forwarded to the FCC's Do Not Call registry number. Maybe that will stop at least some of these jerks.
