Poor service from McDonald’s

I placed an order with McDonald’s app and they debited my money. On the app I received a message that says “Your request is being processed”. I had to call customer care and was told that my order didn’t go through but they did receive payment and it will be refunded in 24hrs time. I am told the is nothing that they can do, I cannot even give me a voucher as I already paid. If I want to order food, I need to pay again. How can they inconvenience me and just say sorry, there’s nothing that they can do, I have to wait for tomorrow? What should I eat since they decided to take my money? I am so unhappy with their service.
