Fnb failed deposit and non-refund

I deposited money onto one of the FNB offsite ATMs at Kagiso mall and the deposit failed but i did not get my money back. I later went to my nearest branch in krugersdorp (president square) to lodge a a query to claim the money back. This was done on the 19th of november and i was informed that the matter would be resolved within 7 working days an the money would be credited into my account. This has not happened. I then went again to enquire on the 29th november i was told that the matter is resolved yet i still have not been credited. I went again today (5th december) and i was informed that it was resolved and the case is "closed" yet i still havent recieved my money and there is no 1 in particular that i can call for assistance because apperently the department that deals with this does not have a phone line
