Such a disappointment Mac donalds Craighall

I ordered from MacDonald Craighall this evening. Instead of three coldrinks for three meal they have me two..only two chips for three meals. All they did when I called they said sorry I need to complain on the uber eats platform. Not sure why because the food was sealed. Clearly they made a mistake and that was the end of it from their side. Such a disappointment seeing that I always order from them and never had issues.
