Please stop using Covid 19 as the excuse as to why calls are not being answered - Telkom, good service has never existed in your client care manuals

Have tried contacting Telkom Billing department for about the 4th time with absolutely no success! Issue we face: Telkom ADSL contract was cancelled in on the 17 April for 18 May. ADSL connectivity ceased on Sunday, 17 May. 30 May, debit order comes off account and additional statements received reflecting the credit. I would like clarification on how to recover this credit as the contract was cancelled as required by your offices and undertaken by ourselves timeously. Question: When do Telkom staff actually operate or have you shut your doors officially?
