UBER EATS took my money

I ordered a meal from Nandos NelPark amounting to R229.80 that was debited TWICE from my account, amounting to R459.60. THE FOOD NEVER ARRIVED. MY KIDS SLEPT HUNGRY!! THE ORDER IS NOT EVEN LISTED IN MY ORDER HISTORY. PLEASE REFUND MY MONEY. I have sent e-mails and I'm being referred from pillar to post. Their website "HELP' button is not even relevant to my situation. No one is willing to help. All I know is that I want my money paid back into my account.
