Do FNB Atm deposit at your own risk. In Need of stress, Deposit cash at FNB atm

Failure of FNB to display use our Atm deposit at your own risk is at best malicious and misguiding clients. On 30/4/2018 evening, I had an unsuccessful cash deposit transaction, which I had to dispute in the branch on 2/5/2018 at 9am. I was advised at the branch (around 9am) on 2/5/2018 that I would receive a reference number by end of the day, which I am still to receive,,, and its almost end of day 2. Problem here is, I have financial obligations, and you have made your processes cumbersome to allow yourself time to unduly benefit from the poor patrons. Where is the ref number as promised and when will I get my money into my account. I would appreciate, if you could provide warning that sometimes you rob us of our money for some days when we do ATM deposit.
