Pathetic service from Uber eats

I ordered a big Mac meal with jelopeno sauce on the side. I got some string sauce instead that they put in a lid of a cup did not even close it the burger had the same strong sauce on. When I opened the app again I rated the experience no one got back to me. Couple days later I sent an email on the app they got back to me n said they can't help me bcoz its out of the 48 hour period the more I tell them I rated the experience n displayed my frustration on the app they still refuse to help me
