FNB *****ing money from my account

I have some major issues with FNB at the moment. I realized that every time I withdraw from an ATM overseas and I do NOT get the money, that FNB is taking it out of my account. I phoned (and waited and was transferred multiple times, as they do) and spoke to a call center person who said I need to fill out a form for EACH transaction and then FNB will determine which transactions were taken out (without me getting the money). They will then refund me apparently. I was surprised and very happy to see they started to refund me for the last few transactions, but then FNB started taking out the money AGAIN with the transactions that I assume I did receive the money for. I filled out 59 forms and still need to fill out more for transactions done overseas - I am now scared to do this as my account is getting cleaned out by FNB. Every day more money is taken out! I have phoned, emailed my "personal banker" Megan de Kock and still nothing is being done. It is getting transferred to the ***** apartment and I am still without money! My money! I have an appointment with my lawyer this week to discuss the matter, but need an answer from FNB - a definite answer. I need the money back as I need to buy flights back to SA. I will be closing my account first thing when I'm back in SA. This is the worst service I have ever received from a bank and I am literally scared to use my card / fill out a form as FNB is *****ing money from me.
