Frustrated with a suspended account

I am so annoyed with Webafrica. I changed my bank details on their dashboard/portal and they still went and debited my old account.

An agent name Thato confirmed that I can use Standard Bank details that I used before to make an EFT transfer. Now I'm without connection and money that I paid now needs to be refunded and I need to make payment again?

So many agents through the chat bot could not help us. You take forever to respond and yesterday Iman confirmed that the money will reflect on Saturday (8th Jan) so I can make payment again.

So frustrating. Please can someone fix this as I cannot wait another day longer to get connected.
