Poor service and skills from drive through

McDonald's in vangate is the most terrible franchise in cape town , today the drive through girl did what no company can allow a worker to do , that is to walk away from a client still ordering ,her etiquette first shows she is I'll trained and her customer service skills is so poor she can't even smile to save her life , the nail on the coffin was to ask me to call the order I just placed , when I asked her to repeat so there is no error on the order, she should be placed in the food prep section not in front taking orders ,how can one wait for 10 munites in a drive through with no traffic Please macdonald's south Africa bring back the mystery customer so you can see where your service is poor at serious if you still value ur customer..
