Disgruntled subscriber

I'm very disappointed in the customer service and being misled by Dstv. They advertised their new add on movie channels but when I opted for it, I found out it's only available on 1 decoder even when you pay for extra view???? How is that possible when you pay a subscription for extra view meaning the same channels should be shown on both decoders. This is a reap off from multichoice. I'm so angry and thinking of canceling my subscription. They should have made it on their advertising and not tell you when you have already signed up.
