These people were stalking us too.. File a police report then give the report number to your phone company.. They will go in and block the Real number they are calling from..
they have multiple numbers. if you have call forward feature on your phone, you can add the numbers to call forward to (888) 382‑1222. that's the number to the 'do not call registry'. each time i get a call, i add that number to my call forward list. now when i get a call from them, i hear a short ring on my phone. i get the satisfaction of knowing the caller will hear 'welcome to the do not call registry' when the call is answered.
These people call me at least twice a day, sometimes four times. The always call when my baby is napping. I'm also on the Do Not Call list and I've also asked to be removed from their calling list, also receiving more sales talk about solar. I asked to be removed three times in one call. After that call, I received three more in three hours. I've reported them the Do Not Call site. https://complaints.donotcall.gov/complaint/complaintcheck.aspx
