HARRASMENT Brooks and Luyt

I have been receiving SMS'e and phone calls daily from this company. I don't even have any debt, and the person that they are looking for is not someone I know. It's getting to the point where it's affecting my work. I have contacted them telling them that they have the wrong number and person. But they keep calling and sending SMS e. I have blocked over 50 numbers already. But they just get an new numbers. Once a call centre agent called me and cursed at me. Saying they have f*k*l of me! It doesn't help to keep asking them to stop. My only resource is to start harassment proceedings against this firm as I again received an SMS in this regard today.
