Worse service ever

I have been paying DSTV religiously even though the thing plays when it wants to and the repeats of programs are irritating, I called in a week ago because the decoder just keeps on searching I was then told to take the thing in for testing, then I was told the decoder is outdated and I need to get a new one, I then got the new one-installed everything called the call centre on the 24th then I was told I needed a technician to come out and do something about the signal"like seriously I have to pay for a technician after you guys have decided to upgrade your software and now that becomes my problem? I paid you a full month service while I was only using your service for half the month because your product is outdated? Do you call that service? You decided to upgrade your product how does that become my problem? Why should I be the one paying for the technician? If you decide to change your product then you should carry this cost, this is unfair to your customer as you guys are not upgrading your product to give us a better view when it rains. So why upgrade the thing if it does the same like the previous product.
