Telkom are huge ******

I cancelled my subscription on the 4/11/2020. They disconnected the service right away. As far as I know I got billed in advance so I already paid for November. However these ****** are still debiting my account. I stopped the debit order at my bank but according to bank telkom uses different reference numbers to debit your account when you stop their debit orders. You tell me,,,how does an average person like myself afford to pay R900 a month until they can sort out their admin. Are you CRAYZEE in these day and age. They even handed my account over to attorneys. I have all my correspondence of my emails to them. I've been asking around and know of people in similar situations with these ******,,,I can think of much worse to call them...****** is still being nice
