They called me earlier in the day and I hung up. I called back to see if it was legitimate and they gave me the option to opt out of calls. So I did. But at 6 that number called back. I blocked them from my provider. Now I received a call from 516-246-6001. Same thing. Some solar initiative. I told him that I had opted out of the other number they call me from repeatedly and he told me that they only have one number, the one he was calling from. If this company is legitimate their number would not come up as an unknown number. I have now blocked this number as well. Let's see what number comes up next.
