DSTV NOW BUFFERING STAY AWAY.....

I have phone to report Friday that DSTV Now Steaming keeps on Buffering..... BBC Brit channel. If it works resolution shifts between 144p - 4k as i am using an apple TV 4k (no stability). My internet speed is 250mb up and down. Last night couldn't watch CNN news only channel working 101. It is absolutely a frustration and i am paying for this S***. If you phone DSTV they tell you "Oh that is streaming they can't really assist with seeing whats wrong??????" Company owned by Naspers one of the wealthiest companies in SA and shows you how useless companies can get and still take your money because of monopoly.....
