Called today have received other calls from similar numbers to 9254398659 (give or take a couple of digits) people scamming I'm sure of it. I never answer the call and recommend the same for you.
Only thing in the Id is Pittsburg ca.
The solar energy lead pests in Pittsburg have incremented to yet another new number.
'National Renewable Energy Center' solar-energy lead-generation telemarketers.
I have repeatedly explained to them that I was renting and thus a waste of time to call.
This is the next fake phone number increment (probably to dodge call blockers - or lawsuits) from:
925-439-8640, 925-439-8630, 925-439-8620, 925-439-8581, 925-439-8548 ... etc. (new number about every week)
NREC is a "referral company" in both northern and southern California that uses minimum wage work-from-home drones to skype spam-call a computer list of phone numbers to try and generate leads that they then sell to actual solar panel installers.
They violate the DNC list, and will not (or can not) remove you from the list (another violation).
They must have too short a list to have called me over a dozen times in the last couple months.
Do not deal with criminals or the companies that they sell marketing leads to!
If you want solar panels - research reputable local installers.
Thank you for the original posting so the rest of us can benefit from the search result! This number called this morning and left no message. On to blocking this number.
