Disappointing service

I have had the worst experience ever from DSTV in years. Last month i was rewarded with a free upgrade and this month my subscription has been suspended because of an outstanding payment on an upgrade which was awarded to me by DSTV. Furthermore my old decoder which has been inactive for years has suddenly been activated and a Disneyplus subscription has been loaded on it **********ly without my knowledge. I have been a loyal DSTV customer for over 10 years but now at the point of cancelling my subscription.
