Harassed by Homechoice

I am really annoyed by this company. I have been receiving calls from this company every two weeks for the past 4 years or more asking to speak to speak Mrs Takalani and everytime I keep telling them that it's not her, but do they stop calling nooo not homechoice. Consultants have promised to get this sorted with their IT department but still it has not been done even after all these years of me complaining to them. I really feel harassed by this company and I just wish they could just stop calling me.
