Bad service

I have 2 decoders running on 1 account. I upgraded to HD decoders. First HD decoder was installed and activated 28 November along with extra view. Second decoder was installed and activated 5 December with nothing additional. Then the 1 HD decoder's extra view was off. Called the call centre with much aggravation because R200 airtime and an hour later, it was still a problem. Then a consultant upgraded me to premium without my consent. Today, my decoder is off. Called the call centre and the manager advised it was disconnected. So now I want to know who is going to reimburse my airtime and pay the additional costs. At no point in any of my calls did I ask for an upgrade or to be disconnected. The service I received was horrible because they kept putting me on hold to check for the problem. My request was simple, activate the second HD decoder??? Why was that so difficult... I'm angry and highly frustrated. I want my billing rectified as I will not be paying for something I did not ask!!!
