Unauthorized Contract Changes, Poor Service, and Request for Contract Cancellation

I am writing to express my deep dissatisfaction with the service I have received. Despite being a loyal customer for several years, this has been my worst experience to date. In 2021, I signed up for a contract, and three years later, without my consent, my plan was changed from a discounted rate to a full subscription. This was done without any prior communication or approval, leaving me with an outstanding balance due to Vodacom’s failure to manage my account correctly. The subscription had always increased annually based on inflation—why am I now being forced to pay the full subscription suddenly? Additionally, I have been in constant communication with your team regarding my SIM card, which was inactive for an entire month. It is frustrating that I now have to resend emails I’ve already sent to prove my case. What is the meaning of this? As of August 20th, my SIM was still inactive and only restored later that weekend. On August 30th, I requested confirmation of the prorated amount due, given that my number was only active for a few days. I wanted to settle the balance and continue with my contract. Yet, despite multiple attempts, I have been passed from one person to another with no resolution. Today, I was informed that none of my previous communication was received. However, I have confirmation with reference number 002JWaK6Q2TKE53 (dated August 30th), clearly showing that my service request was moved to the TOBI support channels. This proves my emails were received—so why is my case still unresolved? Who at Vodacom is responsible for doing their job? There is a trail on that email sent on the 30th for all this communication sent. Furthermore, I demand that you STOP sharing my number with Elite Mobile, as they are the ones who caused all of this confusion. At this point, I am no longer willing to tolerate this poor service. Please cancel my contract for this 400GB sim with immediate effect. I do not wish to repeat myself any further. I've paid already for a month of August without any services received!!!
