Incompetence from Orderin and Restaurant

This app/"service" is going to very quickly lose customers due to incompetence!

How does: 1) a restaurant not give the driver the complete meal; 2) the driver not check on his app and on the slip he is provided that he has the complete meal; 3) after being made aware that there is food missing, and after speaking to someone at the Orderin call center, does the driver a) mark the item he went to get as "delivered", without b) not ACTUALLY delivering the item?! 4) it take 2 HOURS for my complete order to get to me? 5) the owner of the restaurant deliver my missing item COLD 6) Orderin's chat bot/person think that after 3 HOURS of no responses (basically me talking to myself), that a poor unsympathetic canned response and an off for 2 free deliveries for my next 2 orders is sufficient for the grossly unacceptable customer experience that my wife and I had to go through as a result of BOTH the restaurant and Orderin's incompetence!

I do not believe that this was resolved in a satisfactory manner, at all. In the time it took to finally have a complete order, we could have just done it ourselves in less than half the time. Without paying, and without the headache!

It has been almost 72 hours since my order, and no one from Orderin or the restaurant has called to follow up on us. Clearly happy just to "tick the boxes" (which they can't even do right).

I anticipate a response from Orderin and the restaurant with regards to the above. Should there be none in the next 48 hours, I will escalate this further.
