Unable to close account. Employees do not know what they are doing

I have tried over and over again to close my FNB bank account. When I go on the "live chat" on my Fnb app all the agents revert my query to the next agent. No one can help me. I even tried to contact client complaints... Same story. I received an automated message saying that an agent will contact me. I have made it CLEAR in my mail and live chats that I am not in the Country and that I can only be contacted via email. Employees do not read that I am not in the country. All I get is automated responses saying that my query will be escalated to the next person. I cannot go into an actual bank to close my account as I am overseas. I am disgust with this service. To further my frustration, my verified mobile get ****** and therefore I'm unable to verify my new mobile to receive OTP pins and eBucks notifications. Once again, the employees on the chat is absolutely useless and dont know what they are doing. I need my account to be closed ASAP.
