Unsatisfied Telkom customer

I am super unhappy with Telkom's service. I canceled my data contract at the beginning of September, I was told to go to the branch month of September to cancel. I canceled my contract on 30 September 2024. My account has been debited since then, I went to the Telkom store in Wonderpark 3 times, I was told they were having challenges canceling the sim and they will escalate the matter. I did not receive any communication to date. Last week I called the call center and was told again the matter would be escalated. To date I have not received any feedback, that my account is still being debited every month.
