DSTV is a joke

I had a DSTV account over two years ago, I now would like to reconnect and get told there is an outstanding balance on my account, where I had phoned in two years ago to cancel my account, they have no recorded of my cancellation. They ask me to send them proof of the phone call, what a joke, how would they like me to send proof of a phone call from over 2 years ago from a number I no longer have. So cause the person I spoke to did not do what was required, I have to pay an outstanding amount to reconnect, oh and I was never informed about the outstanding amount, no emails were ever sent to me stating I owe them money. DSTV is a joke and I refuse to pay the outstanding amount. I will rather get wifi and stream everything.
