They just won't stop calling

Can't believe your model is cold calling. This is literal spam. Stop it. No, don't ask for my details so you can remove me from your database (which issue never done even if I go to the effort of opting out of something I never opted into and with which you have repeatedly interrupted my life without justification), just stop phoning people who didn't ask to be phoned just so that you can try to sell your product. Spam. There is no excuse for spam, just stop following this obviously ********* model of polluting the world with your commercial intent.
