ATM Refund not being processed (We cant help you!!!!)

Good day I drew money on Friday *** however the money went back into the atm and I had to do a second transaction whilst the first one was not even reversed. I visited the branch FNB Laudium on Saturday 12/01/2019 it was the ATM no 2. I completed the forms. I was told it will be resolved today. I called the bank they said I must come in again. This is ridiculous I will report this on social media platforms fb etc. Your customer service is non existent. So please contact FNB Laudium since you guys charge to use your services make use of the money by adding value to the customer rather than say you can't help if I don't get the required response I will get my whole family to move their private and business accounts to another bank including my friends.
