FNB pathetic service

On the 31st of December 2018 I went to withdrew money at FNB atm , in Greyville branch DBN, KZN. So unfortunately the money got stuck on the machine when it was about to come out and it ended up going back to the machine. but the slip came out saying the money has been withdrawn so I called one of the FNB employees in the branch and explained what happened, so he told me to go inside the branch they made me fill in the forms and told me to wait 4-6 working days to get the money. I asked them in the meantime what must I do because I need the money now, otherwise I would have not come to withdraw if I didn't need the money. I asked them that I should be left stranded because they have a problem with their machine. The manager on duty went on and suggested that I can apply for overdraft in the meantime while I wait to be refunded of which that was gonna cost me more because charges were gonna accumulate for me not them meanwhile the fault is on their side. FNB has no courtesy and they don't put they customers first, their service is pathetic. I had to work away with no money and the inconvenience they caused me that day is out of this world.
