MultiChoice poor accounts management

Dissatisfaction with MultiChoice service delivery. Since August 2024 my viewing has been blocked and unblocked for no error of my own making. My account is up-to-date. They make many unexplained errors like debiting my account more than the required subscription. They add packages unknown to me and demand payment before they reconnect which I have on numerous occasions refused to do. After long explanations they connect my viewing again and disconnect again the following day! This has been going on since the end of August. It's worse now because it's happening on a daily basis. I'm tired of calling them because it takes a lot of my airtime as their calls are not free and they can't call you back. I've sent them emails in October asking them to rectify the errors on my account but nothing has been done. There's no difference whether you speak to a junior agent or their Supervisors the problem will not be permanently resolved. I don't know what to do, I'm tired of calling them. Please assist me with this matter. I've been a customer of DSTV since 1992 , conducting my account well,I never experienced the magnitude of problems with them until recently. They overcharge me and even add packages I don't know of, I'm tired of explaining myself to them. This is taking a toll on my health as every morning I wake up depressed about this blocking and unblocking of my viewing. Please intervene on my behalf! Thanks
