DSTV can't fix their own mess!

In late June I went onto the DPP explora package. A DSTV installer connected up my explora and My old HD PVR was then linked as an extra view decoder. Mid July, DSTV upgraded their Customer management System and since then I have not had a solid day without a technical problem. First I lost HD functionality on both my decoders, this had to be escalated and then took 4 days of repeated phone calls to the call centre before anyone was able to sort it out. A few days later, my extra view functionality stops. Call centre advises that the decoder has been deleted off the system. The decoder is then reloaded and the functionality restored. End of July I am debited R2000 off my bank account only to find out that my extra view decoder was loaded as a second subscription. After another 2 days of repeated calls to correct the billing error, I now have an E16 error on my extra view decoder that the call centre, for some reason or other, cannot clear, so no extra view again. I am constantly told that the issue is being escalated to a supervisor, I am constantly being told that someone will call me back. I am still waiting for a response from the 'supervisor'. No resolution...at all
