NEVER AGREE TO A DEBIT ORDER

NEVER EVER give Cell C access to your bank account via DEBIT ORDER. Cell C do not stick to the agreed amount, they will take any amount they like. This is what happens when you try to cancel the debit order. They tell you, doesn't matter who you talk to, that they CANNOT stop the debit order. I requested by e-mail, several times, cancelation of the debit order. This is the answer I received: "Should you wish to change to cash payment without any valid reason kindly process payment 5 days before your debit date". So I did exactly that and I send a Proof OF Payment, but at the end of the month, although they have RECEIVED the payment, Cell C attempted to withdraw the fee via the debit order. When it failed ( I stopped it at the bank) they had the cheek to charge me a PENALTY fee.
