Contract reversals

Good day I need assistance to expose the call centre agents from Vodacom who ******* me without my knowledge doing a 24 month data upgrade. When I went to the store to do handsets upgrades I was told that I already did upgrades. After numerous calls and emails to reverse the contracts which is now almost 3 months no success.

I need assistance to sort out this matter and is giving Vodacom SA seven working days to sort out the issue or I will approach the credit bureau for further assistance.
