VODACOM SERVICE APPALLING AND *********

This is probably my first complaint re: Vodacom's incompetence, but looking at their other bad reviews, it seems not unique in my case AT ALL!!!! I cancelled an upgrade on a data contract by returning the Sim that was sent via courier, after some affiliation company of Vodacom, REWARDSCO, bamboozled me into upgrading. On the same day rewardsco AND Vodacom was informed of my decision to cancel (this was between the 4 - 9th of July 21) On 26/07 I receive an email with a Quote for the same, which I rep**** to that I do not accept the quote. After contacting Vodacom and speaking to 2 agents, they informed me that the contract was upgraded on 20/07, without my telephonic or written consent!!!!!!!!!!!! I have responded via email to Upgrades regarding the experience. So Please Vodacom, bring your proof of 20/07 that I gave permission to upgrade. This is unacceptable, as you have now debited my account a month later and I do not have any confidence that this matter is going to get resolved timeously in spite of your promises to contact me!!! But please prove me wrong!
