Telkom NO Customer care

I have cancelled my landline which I had for years with Telkom on 30 July 2018, moving over to fibre on another account. I have paid my last account on 1 September 2018, and Telkom told me that they will refund me for additional payments. Then I received an account in September with Notification fees of R207,43 and R443,02. I phoned Telkom customer line and they told me that it will be refunded. On 23 October, nothing still happened, I phoned Pumeza and customer care, reference number ********** 658 issued, and she said she will log a dispute to reverse the charges, reference number ********** 9 iissued. On 29 November I received another bill for R663,67. I loggend a fault on the Telkom site, and Amanda told me that the dispute is still open. When will Telkom be soring out their mess, this is poor customer service?
