BAD SERVICE

IM REALY FRUSTRATED ABOUT THE SERVICE I RECEIVED FROM FNB CARNIVAL MALL,I OPENED AN ACCOUNT AND THE CONSULTANT CONFIMRED THAT ALL MY DEBIT ORDERS WHERE SWITCHED, BOOOM PAYDAY ONLY TO FIND OUT THAT NONE OF THE DEBIT ORDERS WHERE SWITCHED. THE WORST PART NOW IS I CANT GET OTP NO AS THE CONSULTANT DID NOT UPDATE MY NEW CELL NUMBER. WENT TO AN FNB BRANCH AND NO ONE COULD HELP AMEND THE CELL NO, I HAVE DEBIT ODER TO PAY AND I CANT EVEN TRANFER MONEY TO MY OLD ACCOUNT. CALLED CUSTOMER SERVICES STILL THEY DONT KNOW WHY THE OTP IS SENT TO THE OLD NUMBER. CAN SOMEONE PLEASE ASSSIT ME.
