Very Bad Service, Vodacom is a ****

Vodacom is really not treating me fairly, I added discounted bundles over September on both my contract numbers, and on the 28th September I called in requesting for ALL the added bundles to be cancelled, the agent i spoke to told me that he can only cancel the added data and not the minutes (which was false information), and he confirmed to have cancelled them, but on the 1st of October the same bundles i had requested to be removed were allocated to me. I called customer care, and as a result of the rudeness of the agent i was speaking to i then requested to speak to a team leader, and after explaining my problem to the team leader he promised that he will listen to both the calls (for the 28th and the 1st), and he promised that he shall call me back within a couple of hours to give me feedback, of which i never received... I AM BEING BILLED FOR BUNDLES THAT I REQUESTED TO BE REMOVED FROM MY ACCOUNT AND THAT IS NOT FAIR.
