Customer service in SA sucks

In recent times I have had the worst experiences of my life with FNB. I wait for hours and hours on their chat for assistance, I get transferred from one agents chat to another. On 17/08/2024 3 debits went off my account at 15:46:04, 15:46:12 and 15:46:17. Then the chat agent tells me there's no system issues, then how is this possible? I then log a customer complaint as their chat agents provide little to no help... I get a call (thank you David for calling 18/08/2024) but now I'm still waiting for feedback and an outcome?
