Discovery bank false info.

So I've been having this issue for more then a week now. Where I withdrew money at an atm but nothing was dispensed. I was then told discovery Bank will sort it out.. Then I receive an email stating they will refund my money as it is my food money. They will refund it whiles they take this up futher with ABSA bank.... then when I phone 2 days later to follow up about the refund. The whole story changes and now they will not refund me, they will first retrieve the money from Absa which takes up to 30 days.... Yet I'm stuck without food money....
