No delivery and No appropriate response

I am incredibly disappointed in the service received. Yesterday, I ordered lunch via the Ubereats app. The driver showed up after 45minutes (not the point). Once the driver arrived, he informed me that he delivered my lunch to his previous customer so does not actually have my order. Being upset about this, i atempted to cancel the order and report the incident to Ubereats. Biggest Mistake!!!! All you get is a generic response telling me that I needed to cancel the order before the restaurant started preparing it. How was I to know at that point the the driver would mess up the delivery???

I messaged the "help"chat through out yesterday afternoon and this morning repeatedly explaining but no one actually reads the messages, but just keeps sending the same generic message that i should have cancelled before the restaurant started preparing my order.

Incredibly frustrating and absolutely useless.

I requested to escalate the case and still keep getting the same response and no acknowledgement of my escalation request.
