Multichoice pathetic service

Absolutely poor service. They sold me 2 new Explorer decoders last week on a price lock deal for 2 years. I already have a premium package and was told that a DSTV installer will come and install the new Explorer decoders for me and then they will connect it for me. The 2 new decoders were installed and my old one disconnected but since then Multichoice has not been able to connect my 2 new decoders. I've called more than 5 times yesterday speaking to various multichoice assistants, excuses from it will connect automatically, problems to connect because its a price lock deal, issues because I still have the original package etc etc...the last call I requested to speak to a senior consultant after which she said it first needs to be approved by their finance department. Needless to say, 1 day later and I'm still not able to watch any television. Really considering to cancel DSTV subscription.
