Terrible customer service

DSTV has the worst customer service I have ever come across. They called me for price lock and the consultant confirmed that the new decoder will work with my current setup. That evening I checked and found it wont. I called that same evening and they said they would cancel it. I called pricelock next day and the person that sold it to me confirmed it will be canceled. Even after all this the decoder was courierd to me which I did not accept. I called again on that day to ask why it was sent and they said the price lock was not on my account and I wont be charged for it. Today I checked and I'm been charged double. When u called they tell me that I'm been charged for price lock even after they confirmed it will he cancelled. They do not give feedback on issues logged and have terrible customer service. Was told a manager would call me by 13:00 today and still waiting for that call. The service is shocking and I'm appalled that this is the service a customer of over 15 years is getting.
