Cancelling your contract with Cell C will incur additional charges

I called Cell C in June 2026 requesting that they cancel my contract. The agent I spoke with advised me that since my contract ends on 2 August 2026, Cell C will charge me for the full month of August 2026. I begrudgingly agreed, as it felt as though I didn’t have a choice. You can imagine my shock when I received a statement from Cell C informing me that they would debit R703.66 on the 25th of September 2026. I called Cell C on the 4th of September 2026 with the aim of finding out why I must pay this amount when the contract came to end on the 2nd of August. After being put through countless agents, I spoke to Tshepiso Morena from customer care, who assisted me with opening case ***. She advised that Cell C would contact me within 2 working days. I called Cell C today (11/09/2026) to find out the progress of the case and I spoke to Wilson who advised me that the case is still open and Cell C would reverse the charge, but I should keep calling to track the status of the case? How does that even make sense?
