Refund

Vodacom shared my personal information with Mondo, they let Mondo called me on their behalf for contract renewal only to find out the agent from Mondo gave me false information about the product. I called Vodacom try to enquire about this they told me call Mondo, I called Mondo as from September 2024 for them to cancel the contract they managed to cancel it beginning December 2024 and they collected their device. Now as from December 2024 till today I'm struggling to get my refund for this device they telling me it's Vodacom who was debiting my account so they are the one to refund me... Vodacom and Mondo when can I expect my refund because you have your device with you. I'm very disappointed in Vodacom sharing my information without my consent.
