CELL C ****, 5GB PINNACLE CONTRACT CANCELATION

I signed up for a month-to-month 5GB pinnacle data contract with Cell C in August 2021. I have been trying to cancel my contract with them since last year as they failed to send me statements or montlhy invoices.

Today, I got hold of a a customer service agent who tells me I have to pay R1200 for a cancelation fee, claiming that all month-to-month contracts were converted to binding contracts and mine would end in August 2023. THAT IS NOT WHAT I SIGNED UP FOR WHEN I TOOK THE CONTRACT. When I took the contract a sales agent called me, why when you change packages, you only send emails and not call clients for a drastic change that will have a financial impact on the deal?

So, you're able to send an email regarding a change in contract, but fail to send me even one statement???? Balance me here. Show me where I accepted the new change? I don't want this contract please cancel it and reverse data/minutes allocated to my number immediately!
