Not checking UberEats orders

Third time that we place an order through UberEats and items missing. First time we got told to come and collect our chips. Did not give us fresh chips, was the packet left behind. Second time driver spilled our milkshake and just said sorry bad packing. Had to fight for them to deliver a new one. Latest was items missing from order and UberEats gave as a R1 credit. How ridiculous is that.
