MISSING MONEY

HI, I did a international transaction on Wednesday. Until today the funds are not reflecting on my account and FNB is giving me the run around. They saying they returned the money to the senders country but not directly to the persons account. The money was transferred from Lesotho to FNB sender confirmed with her bank and provided valid reference. FNB SA is saying they sent the money back to Lesotho. Initially they said if the money is reflecting on their GL account they would credit her account, but now they decided to send the money back to Lesotho. and a email saying the money is not with them.

I NEED THIS MONEY URGENTLY I NEED TO PAY MY RENT, FROM THE START THEY NEVER TOLD US THAT THE ACCOUNT DOES NOT ACCEPT INTERNATIONAL TRANSACTIONS. they said it's a normal bank account.
