Overcharged!!!!

Dstv is a nightmare and a pain to deal with queries. I have been a loyal customer for ten years and more. They erroneously changed my monthly subscription from 409 to R539, now they have disconnected me because I have laid a complain with their customer service. They kept on saying they have escalated the matter and will sort my account and revert back. I think this type of incompetency is unacceptable and cannot be tolerated, why block my account while you have been overcharging me since April 2021?Do I just continue paying while you keep on overcharging me on month to month.
