Vodacom youtube and video tickets DO NOT work. Rather buy other bundles

hi Vodacom

I am generally very happy with all bundles and tickets etc but your video/youtube ticket never works. I have tried about 3 times now over the span of a year but I cannot watch anything on youtube. it is not my phone, because the moment I buy normal data or connect to wifi, youtube works like a charm. i have bought 1G for R8 youtube data this morning and I tried throughtout the day to connect but there is just no action.
