Bad experience

I called FNB this morning seeking assistance for an unauthorized transaction on my account, I have spent over 30 minutes talking to different departments which is the Debit Order, *****, Collections and Customer Service and non of them were able to assist me. I'm being told that the transaction is a debit order and then debit order tells me that they can't see it on their side and ***** tells me that it is a collection and then collections tells me that it is a debit order. I love FNB and I have been with them for over 10 years but it seems like we have that love and hate type of relationship where I want to leave them but I still would like to stay with them. Please sort my issue out or close my account, it is as easy as that.
