UberEATS poor customer service

Last night I ordered some food on Uber eats. The driver got there earlier and only called as he was leaving. I sent a text saying I'd meet him at the gate because I couldn't get the code, but he had already left and when I called him he didn't take my calls. I called the restaurant directly till 2 hours after the order so I could just collect it myself but they kept saying that the driver never returned the order. My toddler's supper was in that order. I reported this on Uber eats but they said they can't doo anything because the driver followed the policy. I told them that I have evidence that the driver called me as he left and probably when he had already left and that he wasn't answering the phone but I still got no assistance. I bought the food but I couldn't get the actual food or my money. Why wasn't the order returned to the restaurant after he cancelled?? Why wasn't he answering his phone? Why did he only call upon leaving? And why is no one from UberEATS doing anything about it??
