Receiving incorrect communication

I am constantly receiving communication for outstanding debt for a Mr Van Vuuren - MBD Ref No: ***. I am tired of calling the call centre requesting to have my email address removed from this account as this man is a serial non-payer of debt and I am getting all his notifications. This is ridiculous. Despite the phone calls and emails I am still being harassed. Called the call centre again this morning - he is not paying his bond nor SABC TV licence and was told this is the contact email address they have - how do you link my email address to this man! The previous time I called the call center I was asked if I know this man. No I don't!
