Vodacom Ignores customers instructions

On the 5 May I contacted the call centre regarding taking out a contract - the Red Core Package - 200 Minutes,, 14 GB and 126 SMS's I specifically said that it was only to start on the 1 JUNE. I am (or should still be) on a Smart Sim only month to month package until the end of May. I spoke to a Desire Gounder, Durban branch at 13:00. Spent 17 minutes stressing that it must only commence on the 1st June and was assured this would be done. On the 8th May I checked to see how many minutes etc was left and the sms received stated I was on a RED 7GB 200 minutes etc package. I then proceeded to call Vodacom on the 8th at aprox 15:11 and spoke to Vuyo from PE - call lasted an hour as the call kept cutting out. He assured me that I was still on my old package. Just to make sure I called in at a Vodacom store today, 9 May and was told that I was Definitely on the NEW package! What happened to the Consumer protection Act? My instructions to Vodacom were completely ignored! This is the reason I do not WANT to take out a Contract! Vodacom you need to give me an answer and revert back to my old Smart SMS that I was on and ONLY change it on 1 June as requested and confirmed by your reresentative.
