DSTV unable to resolve account errors

Just hope if you're a client and you pay annually, that your decoder never goes faulty as you'll have endless problems with DSTV unable to resolve it. I'm paying annually and I've been struggling with DSTV for 6 months now after my decoder went faulty still under guarantee. I'm staying an hour's drive from DSTV in Randburg and had to drive in to get the unit tested. It was confirmed to be faulty and replaced under guarantee. When I got home the new unit didn't work. I drove an hour back for them to tell me the system is off I must come back another day. Another day I drove back to get a replacement unit which then worked. Since then I get disconnected every week although my full annual subscriptions are paid until Jan 2020. Apparently they've loaded the replacement unit on monthly so every month it shows account in arrears. I've spent 4 hours on the phone, spoke to 3 supervisors (every time holding 35 minutes to talk to a supervisor), been promised every time it will be resolved and they'll phone me back, which never happens. Every time I lose all my recordings due to no service. I'm so fed-up with DSTV as it's an absolute waste of time. I consult and it's a huge loss to my revenue to sit on the phone every time and it's still not resolved. This is why customers leave DSTV. Not only are the services expensive but which customer would stay with this level of frustrations. When I phone to get the names of the person I've dealt with I'm told by the help desk I'm not a very nice person because I'm so frustrated.

When I ask to talk to the Customer Manager I'm told they're not allowed to put me through to him/her but I must follow procedure and write to ***
