Highly disappointed

Today i have ordered food my order had to arrive at 12:15 when i checked the app to text the driver he advised he is lost i re-typed the address for him amd he never responded after a few minutes when i check the app says order completed - i went on the app to complain about my food not arriving the lady on the chat machine couldn't assist me and left the chat with out acknowledging my complaint-how can a driver complete a order when it had clearly never arrived to me and this is the second time im having a matter with uber eats with my food
