Zero star for UberEats

It is a pity there is no zero star. I really wish they are getting rich by ripping the customers off. You have no clear/visible processes on how to report issues of non delivery of orders but you have the audacity to reject peoples claims for refunds on the basis that we only have 48 hours to report an issue. Where is it written? How do we even know where to report these issues? Your phone numbers don't even go through. Never again! I hope my money at least made a difference or an impact in someone's life.
