I’ve been continually getting a SPAM call at my desk (I work at a University!) from “Solar Inst. Srv” at 929-202-8984.....another illegit "Solar" company for sure!!
I have done the same as you, today they have called 6 times, I even talked to a "supervisor" told him I'm 78 years old on S.S.. he was adamant about sending a guy to give me free information. Even when I told him I can't afford anything. Verizon phone co. said can't block telemarketers ?
