FNB money missing

This is now the 3rd request I have to log, previous complaint logged under ***NF. The previous feedback I received from Sunitha was that my money was returned to Citibank as there was no mention made of my BMO Canadian bank account. However, after asking BMO to contact Citibank to find out where the money is and seeing if they can trace the money with the references provided, they informed us that the money was never sent to/ or received by Citibank. Can FNB please contact Citibank and request them to return the money to my FNB because I cannot do this anymore, this has been 4 months and no one seems to know what happened to this money.
