African Bank Call Centre Harassment

For the past two months I have been receiving calls from the African Bank Call Centre two to three times a day, starting as early as 7am and continuing beyond 7pm. Each and every time I speak to one of the call centre people I inform them that they have the incorrect phone number for the person they are looking for. I have requested numerous times that my number please be removed from their system - to no avail. I have now taken to asking to speak to a supervisor and without fail, each and every time I ask, the phone gets put down on me. <br> <br> I am not and never have been a customer of African Bank. This behaviour is tantamount to harassment and I would like for it to be addressed immediately.
