Tired of trying

This Company became the worst. Been doing business with them +- 20 years and recently moved house. Then covid came . There was a miscommunication on part of my installation which the installer came to fix immediately after I called. I noticed that Multichoice deducted Netflix whereas I was paying it separately. I send them bankstatements to proof it and to proof I was paying for even Showmax...yes and I am a Premium member from day 1. I am sending emails and making calls to resolve this matter...but still they want almost R4000.00 from me???????How because if you don't pay upfront you can not watch.....How can they Bill you for not viewing????????? I am tired of trying with no positive response!!!!!!
