Youtube data is a joke

What's the point of offering separate data called youtube data, and vodacom video ticket data, and I don't know what other different type of data they offer if one cannot use the Fu#$ing data???? Is the blady data there only for specs and boechies? I keep recharging data thinking that I can happily use the damn youtube data that I'm suppose to get for free which I do indeed recieve cos I can clearly see it, however after spending hours watching youtube videos I am then notified that I am out of data. So why the hell is my anytime data bieng depleted while watching youtube videos??? And then I recharge my data again and recieve my allocated youtube data along with my anytime data but only my anytime data is getting depleted. I can understand if I was using the data for other things but I'm watching youtube so what exactly is the point of accumulating so much youtube data if all its good for is just to remind me just how much I've accumulated but can do absolutely jack with it
