Money swallowed by atm and 2 week's later no refund or positive feedback

I did an Atm deposit on the 9th of October into Nedbank northgate around 8pm and the money got swallowed by the atm giving me no receipt of the transaction . I have reported this matter to their stuff and was promised resolution within 4 working days. To this day I haven't got any refund and I was informed themail first agent entered incorrect information and the query was discarded. The second agent spent over an hour in a call saying she's logging it with the relevant department. 5 days later I come back to enquire only to be told she never logged anything and gave me a useless reference number. Agent 1 Nyameka, agent 2 Carol. I have spent my time and petrol coming to enquire about my money and absolutely nothing has been done about it.
