Bad service from mochachos

I bought two nacho burgers from mochachos bedfordview through uber eats... Unfortunately the one burger hardly had any nacho crumbs, I buy these often as its one of my favorites from thm, when I called mochachos they told me there is nothing they can do about it... As its an order through uber eats, lol does uber eats make the burger??? Bad service from the manager, truly pathetic indeed.
