Sheetz review: food

Today I ordered 2 hot dogs with chili, cheese, and onions and whoever made my food didn't put the chili on it. Also a couple days ago I ordered a salad from the same Sheetz and whoever made it put chips in my salad when I didn't order chips. What can be done about this because I am really upset about this? The workers there should really start paying attention to the orders that come in better.
