McDonald's N1 city where you wait two days for your order.

So I order from McDonald's on Thursday the 21st through the app. McDonald's N1 makes my food and they drop it at my place. My milkshake is missing. I tell the delivery guy and he says he will be right back with the milkshake. So I go inside and start eating waiting for my shake....that never comes. I find a long hair in my Fries and proceed to through the fries away. So after waiting an hour I call the contact centre and a lady assures me she has sent a request for them to bring me my Shake and a new batch of fries. Its now Saturday morning the 23rd and still nothing. No call from them either which the call centre said they would do. So that's money down the drain.
