No response received for early upgrade from call centre agent and on email.

I spoke to Sansdiso from customer care last week with regards to my account for the early upgrade I took in 2024 July. I asked why will I still pay for the handset until 2026 December as it is 24month contract. Surely it should stop in July 2026 as I paid for both early upgrade phone and previous contract (precious contract till it ended). I should only pay from July 2026 till December 2026 for allocations. She did not seem to understand me properly and the answers she gave made no sense. I asked her to send me a breakdown on email of what I will actually pay from July 2026 until end December 2026 but she did not email me still. I sent a complaint to customer care email and no response either. I sent a follow up and still no follow up. I need to know why an early upgrade I must still pay for another 5months extra. I need these answers please because this then seems unfair as vodacom is charging extra for early upgrades. Please I urge everyone do not take a early upgrade. Boycott vodacom if possible. This is unprofessional that I received no response back still. As is when I took my contract I was charged extra for allocations I did not ask for and now this.... Really unhappy customer.
