Charged for canceling my UberEats order!!

Sunday the 27th of October I had canceled my order on Uber eats because I ordered by mistake. I waited for 3-5 days for refund to enter into my account. Friday the 1st of November I tried reaching out and they said they can't refund me because "We're sorry to hear about your experience, but this order is now outside the refund window." How is that possible without alerting me to keep requesting my money!! I canceled the order within 5 minutes of ordering. How is the driver compensated with an order that wasn't even picked up from the restaurant? Furthermore there was a service and delivery fee, isn't that enough to compensate the delivery person??? The restaurant didn't even proceed with the order!!! No ways, UBEREATS!!!
