FNB Forex won't give me my money!!!

On Friday 16 November, a friend in Dubai transferred money into my account as a gift. It has been over 10 business days and I have not received the money. I contacted FNB, I was put on hold for almost 30 minutes before I was put through to an actual human to talk to. I was told that the bank received no notice of the incoming transaction, even though the bank in Dubai told my friend that the transaction was completed successfully. FNB told me that the sender was required to give me a MT103 form, which the sender did. FNB then stated that "the account number used by the sender is the incorrect number and will not be received by FNB", even though the account number that i gave the sender is correct, and the sender input the account number correctly every time that it was required. The sender contacted her bank and they confirmed that the account number and details are correct and that the transaction was sent successfully to FNB. I contacted FNB once again, and once again i received "We refer to your email and advise that as we have stated the account number provided for your account is incorrect..." in response. Only this time, FNB is sending the money back to the sender - WHICH MEANS THAT FNB RECEIVED THE MONEY FROM DUBAI BUT STILL INSISTED THAT MY ACCOUNT DETAILS ARE WRONG.

So what the f**k FNB? Why won't you give me my money? Why are you withholding my funds when all the information that we have given is correct?
