Overcharge on Account

In May I called Multichoice call centre and cancelled the extra view I had on my account. For the following 2 months after I cancelled I got charged the extra view charges. Since May I have made numerous calls to get my account fixed but nothing. <br> This morning I contacted the N1City branch and now was told that I had to proof that I cancelled the extra view and that I had to proof that I have called the call centre querying this matter. In other words what I say can be queried but, what happens at the call centre is fine . Seriously? <br> If you do not pay your account on time your serves gets cut, but when Multichoice makes a stuff up you have to beg them to fix the problem no matter how many phone calls you have to make and the cost involved.
