A similar thing happened to me. I still have an email that says "your order was cancelled but we'll refund you in 3 weeks". Three weeks later I still had no refund but since so much time had passed, their support refused to consider my complaint. After trying everything I could think of I eventually reversed the charge with my bank which took another 4 weeks or so. Then shortly after that I tried to book a taxi through Uber (not UberEats) and was unexpectedly charged the original amount for my cancelled food order. Again I had to get that amount refunded through my bank which again took weeks.
Most people will not bother to get their money back. Uber's business model is literal theft.
