DSTV PRICELOCK DISASTER

I entered into a pricelock 24 month contract with DSTV on the 5th of March and was told that I will be getting a Explora decoder,wifi connector and installation together with a 24month compact subscription. All for the price of R489. I chose the option to include another decoder for R49 which I was going to use for extra view. My fee in total was to be R538. To date I have only received one decoder(the extra view decoder). I have also been paying R560 which is more than the amount I agreed to on pricelock contract. Todate I have been on and off phone calls and have sent countless emails and yet still no primary decoder. On the 19May was the last time I called and sent 2 emails and was told that the courier was given the decoder to deliver to the installer and that I will get an update. And again no update,no decoder and absolute silence as usual. I have tried and now I am extremely exhausted.
