dstv explorer instalation nightmare

I have puchased a DSTV explorer for R899 a month including instalation. I have this explorer for almost 2 weeks now and it still has not been installed, i have called almost 20 installers on the list that dstv provided and after sending them an sms they also sent me a few numbers. 1 person arrived at my house at 9pm at night without the dstv dish, they said he will come the next day and just never showed up when i called him he shouted and said he was busy. i have since tried contacting abt 10 more installers and they either do not answer or say that they are not on the panel, can dstv please send someone to instal the explorer, u guys advertise so widely and you are a big company i cannot understand how have service providers that provide the worst service ever....when we called the call centre they say they cant help us, we need to use the list to call an installer and that they will escalate the query, when will this be, how long must i wait to have this installed....disgusting service
