Half my food ******/missing and Checkers Sixty60 expects me to wait until Monday?

I am absolutely disgusted with the service I received today. I placed an order through the Sixty60 app, paid in full, and when the delivery arrived, half of the food was missing.

When I called customer service, I was told I have to wait until Monday for an "investigation" before I can even get a refund. This is theft. You have my money, I do not have my food, and now I am expected to sit hungry while you "investigate" your own delivery failure.

I want an immediate refund to my wallet so I can actually buy lunch today, not a promise of a credit in 48 hours. This is pathetic service for a loyal customer.
