Unhappy with Multichoice service

Last week Thursday we had the explorer installed. I had called Multichoice to connect the explorer, pvr and hd decoder. The latter 2 was to be extra view. The consultant explained to me that I cannot use the hd decoder as its outdated and I need to purchase a new hd. my next question was if I purchase a new hd decoder I can connect the pvr and hd as extra view and the consultant rep**** yes mam. So my installer left tp purchase the latest hd decoder. he arrived to install the new hd decoder as extra view. The explorer and pvr is now connected so I phone multichoice again to now connect the new hd. Only to be told that you cannot use pvr, hd with explorer. you will need to hd's with the explorer or 3x explorers. My question is why was not I informed the first time that I needed 2x hd decoders etc. Multichoice call centre agents don't know the products and they don't have the correct information to pass onto customers. Mutlichoice is just a moneymaking business. They don't care about the end user. I am still waiting for a representative to call me regarding this issue. On Thursday I had made 5 phone calls to multichoice. I am still experiencing problems after the installation was completed and its not the installation. E16 error message keeps popping up on both the extra views the call centre has to reset the signal. Last call I was put on hold while the consultant had to use another computer to reset the signal. Not happy with the service received. Here's hoping an alternative viewing system will come into play soon.
