Bad service

Good day,

I am not happy with the service I am getting at Telkom. I app**** for data LTE contract on the 7th of May 2020 and cancelled it on the same day. The agent confirmed that the contract has been cancelled and then Telkom debited my account on the 8th of May 2020. I have phoned 5 different people at Telkom asking them to reverse my debit order and no one can assist me. Two supervisors said they will come back to me and assist but its been 5 days and they have not called me back. I had to call customer care line for the past 5 days and billing department says they cant assist as its the sales department that must assist me. When I speak to sales department they say its the billing department.

I don't understand why it is so difficult for Telkom to just reverse the debit order as I am not using their service. This is such bad service from Telkom.
