Inability to resolve issues

After numerous complaints to Multichoice and documenting my case on hellopeter. My issues regarding incorrect billing and the ability to resolve the matter has not been completed. As of the last conversation had with Multichoice on 03/11/2015 and 04/11/2015, I was promised that I would get feedback regarding the incorrect billing to my account within 24 hours. It is now one week later and I the issue was not resolved, nor have i received feedback on a resolution. This is become very frustrating and inconvenient as I have to constantly make contact with multichoice and due the large amounts of calls they currently receive I am put on hold, which results in further cost incurred by myself. Multichoice has debited my account over the last 4months for the incorrect amount and therefore needs to credit me a large amount of money.
