Uber eats Bad Food delivery service

My issue is that I want my refund. After placing the order on the 16th of May and it was not delivered although I am told by the restaurant that the driver picked up the order. I tried to complain several times about it and what am told is that because I previously received a refund for another order I will not get for this order. How is it my fault that you don't meet customers expectations. Why are you punishing me for your drivers who fail to deliver even did not have the curtacy to call me. Why is my problem that contact details of the driver is not even on the app or website.
