Bad attitude from staff, missing items from order

I have never experienced such terrible service from a McDonald's restaurants ever, I am highly disappointed at the staffs attitude in McDonalds Harrismith bergview, the staff have no sense of urgency, the lady at the till had a terrible attitude, my order was incomplete, my cappuccino was cold I had to ask for sugar and a stirrer and my bottled water , my son didn't even receive his toy, mind you the bus was leaving us because the staff were taking too long, I redeemed my points for a doughnut for my son which I didn't receive either in terms of that, I would like to know what will happen to my points? I am highly annoyed.
