Overcharged by Multichoice

I was overcharged by Multichoice and when I called their Call Centre on 11 July 2022, I was told by a consultant that I have added an Indian movie package to my subscription. I disputed the information and was told to go to the local Multichoice Service Centre to report the matter. The call was cut off and when I called again and spoke to the second consultant, and told her that I did not add the Indian package to my subscription, she literally told me that it was "my word against theirs". I was told that the matter will be investigated and I will be given feedback within 48 hrs. Feedback is still not provided. I want the overcharged amount to e refunded to my bank account today!!!
