VOX TELECOM DO NOT COMMUNICATE! CALL CENTRE NOT FUNCTIONAL

On 28 December 2023 I phoned Vox Telecom to cancel my internet contract. I was holding on for so long, that eventually Vox dropped the call. So I sent a formal Letter of Cancellation to the Debtors dept. & asked them to confirm receipt which they did not. Today, 29.01.2024, I received a new invoice for February 2024 and the account is on automatic debit order. I immediately phoned Vox Telecom at the phone no. on the Invoice and was holding on for 15 minutes and then Vox dropped the call. I phoned again and got through to a service agent whose line was so bad that I suspenct she is working remotely from a rural area. And sure enough the call was dropped again. I have re-sent my Letter of Cancellation today to the Debtors Dept. as I do not have an email address specifically for cancellations and there is nobody to talk to ask. IT IS CLEARLY IMPOSSIBLE TO COMMUNICATE WITH VOX TELECOM. NOT BY PHONE AND NOT BY EMAIL! IN THE MEANTIME THEY ARE TAKING R1,000 FROM MY BANK ACCOUNT. I NEED SOMEBODY TO PHONE ME BACK OR RESPOND TO MY EMAILS URGENTLY.
