WORST SERVICE EVER

Worst customer service received from McDonald's Galleria!!! I am a hindu and I had 3 encounters with McDonald's Galleria... the staff are negligent!!!! the first incident where my nephew was given a beef burger instead of a chicken and he had taken a bite of this burger which is totally against my religion!!!!!! the second I was in the store when I was given a beef burger instead of a chicken.... the manager just takes it and gives you the correct order without fixing the situation as we can see this is the third instance! Today I ordered 2 burgers from Mr D and I had to bring a beef burger into my house!!! this is unacceptable.... Now I get feedback from Mr D that they credited the amount for the incorrect burger and I must go reorder on their mistake and I must pay for the delivery????? THIS IS RIDDICULOUS AND I NOW HAVE AN ANGRY/HUNGRY WIFE TO DEAL WITH!!! PATHETIC SERVICE
