Disgusting pathetic useless SERVICE!

I actually don't know where to start! I am so fed up, frustrated and appalled by the most terrible and inefficient service from DSTV. I was contacted for the price lock offer, upon taking up the offer and spending over 20 mins on the phone doing the application (I already have PVR and have had for over 5 years) and me specifically clarifying with the agent if I did not require the installation as I am in a communal dwelling (flats). She confirmed I only needed the Explora without installation and it would be a plug in and play from my PVR setup no installation required. WELL this is not the case and I have now lost track of how many phone calls I have made or agents and supervisors I have spoken to and emails I have sent as I am being billed twice every month, for PVR and Explora and NO Explora working as it does not work. I have been advised to reverse the debit order every month and pay just the PVR and that DSTV would arrange to collect the current Explora sent to me and deliver a new package which includes installation. This is going on for 3 MONTHS now and I am tired of calling and speaking to agents and supervisors who all make promises to sort it out BUT NEVER do so! You keep disconnecting my service and then when I reconnect you look and see the notes in the account to reconnect me! you are giving me a BAD credit rating as it looks like I am not paying my account BUT DSTV is not sorting out their mess. Every time I call it is a 30min call at my expense with me not getting any further but just empty promises to sort it out and ending up incredibly frustrated. As promised by yourselves, I need the current Explora price cut cancelled and a new one issued with installation and all monies due from the past 3 months for the Explora credited to my account - PLEASE SORT IT OUT or else I will have no option to escalate this higher!
