Can't get a request through to close accounts

I started a chat at 12:15 (2021/04/30) on the App to close all of my accounts. At 13:27 I was connected to Khanyisile and requested that I want to close my accounts. The banker was disconnected. At 14:13 I was connected to Avishkar and requested again to close my accounts. Once again the banker was disconnected. At 14:41 I was connected to Itumeleng and it is now 15:05 and I still don't know if the request was sent through to close my accounts. This bad service is the reason why I'm leaving FNB.
