Bad Service

I am writing to formally complain about the internet service contract I recently entered into with Vodacom. On 26 November 2024, I called to upgrade my contract because it was going to expire, and I was informed that the package that I was using was on sale, my home internet plan. However, I have since discovered that the new plan is not an upgrade but a significant downgrade. The contract took a 2-month delay because of the Skynet courier to deliver the device. Finally, I got the device for the new contract; the nightmare was on 12 February to find out the data was finished The shock of my life. Specifically, I was assured that the upgraded plan would offer uncapped internet, but instead, I have been provided with a capped plan of only 200GB per month. This is not what I agreed to, and it has caused inconvenience and dissatisfaction; also, now I have to spend more money. To resolve this issue, I request one of the following:

A reversal of the contract to my previous uncapped internet plan, or An immediate upgrade to the uncapped internet plan as originally promised.
