No food no refunds and no response from uber eats

I placed and order via their app money went out from my account but the food was never delivered and it wasn't even reflect on my past orders list...I tried calling and Fail as their number is no longer operational, I tried using an old order to reach out to their help section it didn't work ...a day later the order reflects on my old order list with a not that the restaurant cancelled the order but still haven't received my funds...am annoyed and I just want refund back then I can delete this app honestly
