Non stop calls from Capitec

I am receiving continuous calls from Capitec. I do not have a Capitec account and I don't want a Capitec account.<br> <br> When I answered one of the calls 2 weeks ago they said they are looking for one of their clients which I told them I don't know. The Capitec employee got very aggressive with me.<br> <br> They keep calling me and this not acceptable!!!<br> <br> Please can a manager of this bank get in contact with me.<br> <br> I don't want to receive anymore calls from them!!!
