My telkom wifi contract came to an end on the 6th of August 2023

My telkom wifi contract came to an end on the 6th of August 2023. I contacted Telkom to have this cancelled on the 3rd of August. The agent advised me that the contract was cancelled. I specifically asked when would be my last payment and the agent advised end of August. At the end of August I was debited. I phoned again on the 1st of September to find out if it has been cancelled. The agent advised me that the contract was still active. I was so confused and upset so I asked for the contract to be cancelled and asked for the call recording as to my knowledge I do not owe Telkom anything. Ever since the 1st of September I have contacted Telkom numerous times and spoke to several agents who kept telling me the same thing. They even told me that they will get the manager to call me. Today is the 17th of September and I refuse to pay Telkom any money because as per the call recording the agent advised me that the last payment date will be at the end of August. When I spoke to another representative. She advised me that I will be billed at the end of September. I told her that this is not right and how many times should I call to cancel. I don't think its fair for for me to pay for September because I was advised that my last bill would be at the end of August. I'm so tired of calling and saying the same thing over and over. People work hard for their money and to have an extra R850 deducted although cancelation was placed is ridiculous.
