VOX payment system not working, VOX puts blame on customer

On 31 May 2022, my credit card expired and my bank issued me with a new credit card. I duly tried to load the new credit card details on my VOX account online without success. I also tried to create a debit order via the VOX account online without success. On 1 June, 2022, I contacted the VOX email helpline for assistance. Nobody rep**** or assisted. I again emailed the helpline for assistance and to get the VOX banking details to pay via EFT while they sort out their payment system. Again, nobody bothered to assist. Today, 6 June 2022, VOX issued me with a notice to suspend my service due to non-payment. Again, despite all efforts to make payment, nobody at VOX bothered to assist in fixing their payment system. Yet, VOX is quick to treat paying customers like dirt.
