Dstv Multichoice don't care for new customers

I was previously a premium subscriber and like many others cancelled abou4 to 5 years ago. I decided to start again. When I contacted them, I was told I cannot as my account has a ***** hold on it and I must wait and they will respond in 48 hours. This was a perfectly good account and the issue has nothing to do with me. I gave an old decoder to my gardener with a letter and he promised to change its ownership. I can only presume he never did that and tried to use it, that is why it is on hold. That being said, it is now 100 hours and still nobody has called me. I have tried 5 times to call them back and all I get told is they cannot help and I must wait for the promised callback. Nobody will put you through to anyone who can resolve issues. What a useless bunch. You would think with their business losing so much money, they would bend over backwards to get premium subscribers back. Clearly they don't care and I will revert to other means of streaming. AllI want is motorsport, and their are plenty of other options.
