Cell C Bad Customer Service - NOT cancelling contract after expire

Our contract with Cell C expired 15/10/2022. On 12/08/2022 we have emailed customer care our cancellation letter to give enough time notice in advance. Several emails followed to confirm cancellation and no reply from Cell C. We phoned and they confirmed that the contract will be canceled on 15/10/2022.

Yesterday, 15/10/2022 Debit Order went off with an increased amount to Cell C. On Facebook email Cell C rep**** to me, saying that the contract is now only expiring end April 2023.

Customer Care do not exist at Cell C. This is not the first time they are doing this to us. How many money are they *****ing from people. People just think they have canceled but the contract is still going on and they just taking debit order off your account with your permission for new amounts. I have informed my bank to stop the debit order.
