Unsolicited marketing

I am not a client of this business. I have been receiving marketing calls from this business. I have tried blocking their number(s) but it appears there is always a new number. I have now requested twice (2) that my information be removed from their system as I am not interested and didn't give consent for them to contact me. Yet, the calls continue. I suppose I will have to continue blocking every new number they call from. And, I will never, ever, ever do business with a company like this.
