My money disappeared from ABSA Bank

I made an immediate bank transfer yesterday morning at 6H30 approximately from ABSA to FNB bank account.

I have received communication from FNB beneficiary that i was depositing the money to that FNB did not receive the money from ABSA.

The money have already went out of my account yesterday morning at 6H30.

I have contacted ABSA internet banking consultants several times since yesterday and and this morning, however they are giving me run rounds.
