Vodacom upgrade not what was offered

On 24 November 2021 I was offered an upgrade on 3 numbers. However, the upgrade was not what was offered to me. On 30 November 2021 I called 082 135 to cancel the upgrade. On 3 December 2021 I called *** to cancel the upgrade and was given a Reference Number and was informed that the cancellation of the upgrade would only be completed after the "WeGrowSA Ultimate Vouchers" were collected. The collection number was provided to Vodacom on 10 December 2021 after I had to call Vodacom on 9 December 2021 to again to remind them that he vouchers were still not collected. We are now in January 2022 and the upgrades were still not cancelled.
