Uber Eats *********** and inefficient driver

I ordered food on 29 October from Uber Eats and the driver's phone was not going through and he was unreachable. I communicated with the driver via the apps chat while he was waiting for the order the driver was not responding to all forms of communication and Uber Eats retained did not refund me fully and it was the driver's fault. Uber Eats punished me for their *********** and inefficient driver. I have the call logs and Uber Eats has the chat log.
