Simple service practices!

How many times can one store get a regular customers order wrong? The drivers know me by name, the managers know me by name, I call, I complain , I plead, I post on Hello Peter and still my order takes over two hours to get to my house. Needless to say, my house is literally 3 mins down the road. Absolutely shocking...management are at a loss for words and understand how I must be feeling...***!!! I am so angry I want to drive to the store in clear water mall and make a massive scene.
