Vodacom upgrade

I upgraded my contract in July and agreed with the consultant in terms of the plan and duration of the contract . But when the deal was loaded unto the system, it was incorrectly captured – the details were completely different with what I agreed upon. I raised the matter with Vodacom, they investigated the query and only after two months they told me that my query was valid, and I have two options – to continue or cancel the contract – I objected to that resolution because I felt I was being treated unfairly. On the 21 of September, I was contacted again by the rewards team, they investigated and promised me that they will resolve the matter and load the right contract as per my agreement with the consultant (July 2023). They did a migration of the contract to the deal I agreed to with the consultant, but again they didn’t capture the correct term of contract (it's not captured correctly). I tried to follow up with the rewards but no avail. I have sent several emails (even calls) to the customer care but there is no response at all, I've been ignored. I really feel that Vodacom is unwilling to engage and resolve this matter. Is this how we should be treated if we have issues??????
