Tried to cancel a contract un September, cancellation only put through in November.

Had an LTE contract that expired October. I put through the cancellation in September online and via the phone. Was confirmed that last debit would be 1st November. Woke up this morning the debit still going off on my account. Contacted Telkom and was told the cancellation was only put in 10th November. LTE Service has been suspended since start of November and I have not used the account but was told there is nothing they can do about it even though the mistake is on their end. ********* I tell you... In the time of a pandemic they still try to cheat the little guy of of money.
