FRASTRATED BUSINESS HOLDER

I HAVE BEEN USING FNB FOR ABOUT 3 YEARS FOR BUSINESS, I RECENTLY GOT THE FUNDING OF R350 000 AND THE FUNDS KEEP BOUNCING AND WHEN I GO TO FNB NOBODY IS GIVING ME ANY ANSWER, I VERIFIED THE STATUS OF THE ACCOUNT AND ALL IS IN ORDER SO THEY SAY BUT ABOUT 3TIMES IT BOUNCED BACK, THEN A PERSONAL FRIEND DID THE SAME AMOUNT TO SEE AND IT BOUNCED BACK TO THEM, THERE IS NO REASON WHATSOEVER FROM CALL CENTERS TO BRANCH ,I NEED ANSWER TODAY OR MOVE MY BUSINESS TO OTHER BANK
