Mc Donalds Lenasia POOR SERVICE!

The service at Mac Donald's Lenasia is quite bad. Almost every time I order through Mr. D's food, they give me the wrong order for some reason. Because I work from home and am unable to leave, I ordered through Mr. D. Food. I am now trapped with food that I cannot consume, and to make matters worse, I requested a Stoney no sugar for a diabetic person but was instead given a milkshake. I've had it with the poor service.
