Half Order Meal with wrong Ingredients

I bought a Large Big Mc 2 hour’s earlier via Uber Eats at Mc Donald’s Kempton Park Monument Street To my surprise when I opened the Meal it was a Regular Burger so small they Used the wrong Roll also - a roll without wheat- the Chips were half and the drink. I’m really disappointed with the meal I got its not value for Money after I Craved for it so bad- I would really Appreciate a Refund
