Summer deal bundles are NOT a deal!!

I bought a summer deal data bundle for 15GB that gives access to YouTube premium. The code that Vodacom sent for YouTube premium is not valid when I tried redeeming it on the link Vodacom provided. It is really annoying when you purchase something and the Service Provider does not honour their own terms. What was the point of purchasing the bundle if I don’t get what is promised in the bundle. Not the first time I am having problems with Vodacom’s service.
