Standard Bank customers keep phoning me

I have been called by Standard Bank customers for over a year now.<br> For some unknown reason standard Bank decided I was the contact for Brooks & Luyt and customers keep calling me. Not only do they have my land line number but they have my cell number and email address and they keep phoning me during weekends and evenings.<br> I have tried to get Standard Bank to change the details but they always give me some excuse or tell me it is done but then I get more calls.<br> I am trying this route in desperation.
