so dissappointed at UberEats

im so dissappointed, so much. im never gonna use the uber eats service again. we ordered the McDonald's Big Tasty special (buy one and get one free) on uber eats and we ordered 2 items. we had to return the order 3 times because uber eats delivered the wrong order 3 times. instead of bringing 2 orders they brought 1 all the time and they said mcDonalds is refusing to give them the free meals. that shouldnt be my problem as a customer, uber eats and McDonald's must sort their issues. Im so so dissapointed.
