Bye Bye Web*****ca

I was with them since 2021.I canceled my fibre and was told to pay a R999 cancelation fee. I was never told there will be a fee if i do cancel. The agent told me it is for new customers with new packages and the old customers were kept on the old packages. How does a customer since 2021 not be seen as an old customer ? When i ask for the call recording stating that i agreed with the cancelation, they keep on asking the date. I told them i don't know the date, please check the activation date. Then the agent keep on asking for the date
