Misleading contract and failure to cancell

On 3.9.2020 I called in and spoke with Veronica and requested that all contracts must be canceled as I only want 2of my current contracts active. The consultant assured me it was canceled. Just to find out that the contracts are not canceled. We went to a vodacom store to ask why my one contract was calculated on 36month and not 24months.(we signed for the contract under the impression its 24months, the consultant mislead us). We are requesting the contract be rectified that was canceled as per initial call on 3.9.2020... Failure to rectify and back date the additional amounts refunded will result in this matter handed to ICASA. We also want the contract of 36 months rectified to 24months because we picked the phone from the catalogue, now we paying for another year
