Fnb forex

I am frustrated with FNB, i did a forex payment on the 31st, the transcation was rejected and the money never came back. 8 days FNB has been holding on to my money and none of their consultants can help me get my money back. I was suppose to pay my fee today but because FNB decided to reject my transcation and hold on to my money i am unable to make the deadline!!! I went to the branch they cant help me i have to phone the forex department who are not able to help me. I just need money back into my account including the fees they took as well as the intrest my money gained whilst they were holding on to it!!!!!
