Pathetic mcdonald's shallcross

I visit McDonald's Shallcross and use uber eats to order food, I have complained many times to management, even reviews on Google had no response, it's is absolutely pathetic that this store is still allowed to run, the service is horrible, the food is not up to quality, the mcflurries is purely ice-cream at the bottom with the oreo dusted on the top, not even mixed, it comes in a thin plastic packet that is unhygienic, there is never sweet and sour sauce for the nuggets and they give my daughter jalapeño sauce, she cannot eat it, I am so sick and tired of trying to get someone to take responsibility and help us, it is disgusting that the owners still continue with the horrid service and pathetic food, senior levels need to assist
