Continual theft of hard earned money

In the past 6 months, I've been shocked at the behaviour of FNB. I have been with FNB since I was a child, more than 18 years ago. I have recently returned from a long planned overseas trip. I am a nurse, and it took 18 months of saving. The joyful experience has now been *****ed by the attitude of some at FNB. In December last year I ordered Euro online. This is the first time I had ordered Forex. I placed my order and the money came off of my account immediately. I went to fetch the money a week later, and after all the paperwork had been processed I was told that in fact I was breaking the law because they couldn't give me the Euro then, only 60 days before my trip. I said that the internet site had allowed me to proceed and I was unaware of the 60 day wait. Since it was approximately 85 days, I asked if they could hold the Forex for me, as I had paid it, and I would collect 3 weeks later. They said no, and that I would have to sell the money back, even though I had not touched it - it had not left the vault. The money was bought back at a lower price and I had to incur the expense, which I did as I had no choice. That is 1 of 2 bad experiences to which no one responded.
