Prioritizing speed test for false results

**** Telkom and the way they prioritize speed tests, I get a 10mg/s download on a speed test, but i can’t even watch a 2min YouTube video at 720p without it buffering. You guys are a bunch of ******* that ***** money and give you **** all for what you paying for. I’v called multiple times with the same story of the line is syncing correct keeps arising, but if I download something it’s running at 0,78kb/s and that is far from 10mb/s, please sort this issue out asap as I am a paying customer that is unsatisfied.
