Harassment by Attorneys and I'm not the person they're looking for

I keep on being harassed by these MBD Attorneys on both my Private and Business Phone. The point of harassment comes as a matter of fact that I'm not the person they keep on looking for when they call. I've made them aware of this and they promised to have my numbers removed, however it's almost two months I've been getting these calls and they aren't making my life easy as I have to keep on repeating the same thing over and over. Can you urgently have the issue sorted.
