FNB won't pay back my money!!!

In April this year i made a forex payment to the value of EUR650 to a company overseas, for some reason that no-one has been able to explain to me, FNB Forex department duplicated the transaction so the funds were deducted from my account twice! As soon as i received a notification of the second transaction and realised what had happened i contacted FNB forex department to find out what was going on and they said they would cancel the second, duplicated transaction and request for the funds to be returned to my account. <br> <br> It has now been over 6 months since this happened and i still have not received the money back from FNB even though they admitted that the fault was their own. The personnel in the forex department with whom i have been corresponding via email have been extremely slack in rectifying this issue, i am the one contacting them and i have to constantly chase them up to get an update on the situation<br> <br> They told me that they have sent a request to the bank overseas to return the funds but are not getting a reply. Frankly this is not my problem, it was FNB's fault the money was taken off my account twice so FNB should be responsible for returning the funds to my account!
