UberEats debited my account without authorisation

After ordering an Uber Driver on Christmas day and the payment going off my account, Uber Eats automatically debited my account for R457.16 for an order from 4 August 2023 which was never delivered. They refuse to refund or supply their legal departments details, they simply say I never notified them within 48 hours from the order date, which they actually mean debit date as I finally figured out that you cannot contact them via email but via the app on the 28th. After multiple back and forth, I suggested they then deliver the order that I have been debited for so that I have paid for something in return. I received no response as of yet.
