Demand answers from dstv!

I am beyond angry! Besides having to wait over 2 months from April for my explorer ultra to be installed, and 4 appointments made for the installer to do the job, no one pitched! Eventually on 22 June they arrived and the job was done. I have a premium package and 2 extra views, and the price was confirmed at R1084pm which included the insurance on the explorer. I called multichoice on numerous occasions to confirm that this price was correct, asked if they could email the breakdown of the account to me, but as usual no email! To my horror, when the amount came off my account, it was over R2000!! I spent 40 minutes(my cell phone time!) to try and get answers, and was told that it included another Compact deal that I had ordered on Self Service. I don't even know what Self Service is!!!! And I don't even have another decoder!! Why would I want a Compact deal, when all 3 decoders of mine are on the premium package?!? Then I got a call from a supervisor BRENDON, and he said he would discuss it with the technical Dept and call me back in 48hrs (I have now waited for nearly 2 weeks!)It's totally unacceptable that DSTV don't email you with details of any new package that they decide to charge you for! I am going to take this matter further if I am not refunded the extra amount that I have been charged. This is *****! I would like to hear from the top manager as it is obvious that your supervisors cannot deal with matters like this.
