Harassment

Harassment : For the pass 2 years I've been harassed by OnAir/OneAir on behalf of Multichoice. They have been calling me consistently even month for 4-5 days looking for a Mr Simon whatever his name is. I am so frustrated and feel very aggrieved by this because every time I tell them there's no one like that here and that I've have my number for over ten yes. But they just keep calling. I think my next step should be to file harassment charges against them. Please advise as I am really sick n tired of this now.
