Dishonesty by staff

Hello Peter, thank you for this useful platform. I have been trying to resolve an issue I had with Vodacom which has since been half resolved after I wrote a review here. I am coming back because I keep chasing after the manager who has been dealing with my complaint without success. I had an issue with Vodacom who misled me into upgrading my contract and they changed the terms of the agreement after a month. When I wanted to contract reinstated to the original, they refused and instead requested me to return the handset, which I did. I was promised a refund, however, it did not happen. When I requested the breakdown of the amount that was due to me since the contract was upgraded in August 2023 and terminated in May 2024, I did not get any help. Candice, who has been assisting me keeps on saying that she will give me feedback and to date I have not had any joy. The last communication between us was on 12 July 2024 and in that comms she said that she spoke to her credits department and would call me before the end of the day to provide feedback. I have not heard from her since and am really tired of chasing after her. Is this how this company deals with customers? Where is the integrity?
