FOR HOW LONG MUST I WAIT?

ON THE 12th OF DECEMBER 2015, I WENT TO THE WORKSHOP ATM TO DEPOSIT THE MONEY AND WHILE I WAS TYPING THE REFERENCE DETAILS THE ATM LOGGED OFF. I WENT TO THE BANK AND FILLED IN THE DISPUTE FORM. THE SALES CONSULTANT TOLD ME TO WAIT 6 TO 7 DAYS. I WENT BACK AGAIN, SHE TOLD ME TO WAIT 14 DAYS. ON THE 7th JANUARY I WENT BACK AGAIN, I RECEIVED AN SMS WITH A REFERENCE NUMBER, I WAITED UNTIL YESTERDAY HOPING THEY WILL DEPOSIT THE MONEY INTO MY ACCOUNT. WHEN I GET THERE YESTERDAY, THE SALES CONSULTANT PHONED THE ATM DISPUTE DEPARTMENT, THEY TOLD HER MY QUERY HAS BEEN CLOSED!!!!!! HOW CAN IT BE CLOSED BECAUSE I HAVEN'T RECEIVE MY MONEY!!!!!! FOR HOW LONG MUST I WAIT????? I'M TIRED OF GOING TO THE BANK NOW TALKING ABOUT THE ONE AND THE SAME THING.
