Never encountered a manager like this

Placed an order from Hungry Lion Zevenwacht the past Saturday Did not receive all items then I proceeded to call to the call center agent just told me log a complaint on Uber, which I did not feedback I then went to hungry lion on Sunday and I told the manager even showing my receipt and she says I didn't pay for it although I have proof! Bad client service hungry lion, doesn't matter if the food is how wonderful the way you treat you clients is horrible.
