Harassment of Benefits

I have an account with TFG , I get calls daily for some sort of benefits that I am not interested in, I've told the consultants that I am not interested but one had the audacity to say they will call me daily . I went to a store to get it removed but they failed . I've blocked so many of their calls but they call using different numbers daily, they can call 8 to 10 times a day . That is harassment with a higher grades
