FNB My Service Suite a disgraceful *********** service

I have been trying to resolve an issue since Saturday, 4 January. I had erroneously transferred money to the wrong account and used the "Secure Chat" feature via the My Service Suite on the banking app. On Saturday, I was told the reversal would be done within 24 hours. On Monday when there was no movement in my account, I contacted them again via chat. I was told that the reversal will be done in 48 hours. After the 48 hours were up, and there was no reversal, I contacted them again. I was then transferred to the Credit Card Legal Recoveries and was put on hold. After 8 hours, with no one responding, I ended the chat. I tried again today, 10 January, and am still being transferred, disconnected, and reconnected with a new agent, without any result. I have now been online and in a queue for another hour.
