DStv no longer cares

Took my decoders to DStv as they no longer compatible to Showmax which is not my fault. I was told I need to purchase their new ultra decoders even though I have insurance. I must write a motivation to the insurance to provide me with the ultra decoder, why?? I spend almost 1700 a month with DStv which includes insurance and 2 subscriptions. It is so unfortunate that I am having to cancel my subscriptions and DStv will be at a loss of a premium customer and having DStv since the year 2000. Then on air still sells me a decoder that I am busy paying off because DStv provided my information and was advised the decoder whose software was outdated. DStv after a 24 year relationship this is sadly goodbye.
