FNB duplication of transactions

I am extremely disappointed with the service from FNB. I woke up to find my account in a negative balance due to duplicated transactions, which has left me stranded without access to my funds. What makes the situation even more frustrating is that there has been no formal communication from FNB regarding this technical issue. Instead, I have had to actively seek updates myself, with no clear confirmation of when my money will be returned. It is deeply concerning that such an important matter, which directly affects a customer's financial well being, is handled with so little communication and urgency. I expected far better transparency and care from a bank when dealing with an issue that impacts something as essential as access to one's own money.
