Worse Customer service

I had worse experience with @UberEats I ordered a HAPPY MEAL from McDonald's via @UberEats I received an empty bun with one piece of cucumber inside there was no patty and when I reported this to they told me they can not refund me because the things that are supposed to be inside the bun to make it a burger are free and I asked them if the R77 rand I paid was for the empty bun they did not respond
