Shocking and Non Existant Service

I have been having ongoing problems with signal. Twice before, the consultants were quick to tell me to contact an installer whithout even bothering to try and assist. I can currently view some channels, but many i get the error that there is no signal due to weather. This happens even when there is no weather problem!!!! I phoned the call centre on wednesday and i was informed that it can happen that there is no signal for some channels whilst there can be signal for others. This makes no sense to me. Whilst the person was trying to assist me, DSTV suddenly cut my call!!!! The agents dont bother to try and call the subscriber back!!!! Your service is shocking!!! But you will always be quick to collect our subscriptions. If someone does not assist me i will start looking for cheaper and more reliable service providers. I read from the news media that this is the case and yet DSTV do nothing to keep their customers.
