Pathetic Service

Worst service I have ever received at the Shallcross branch. I visited the store on the 04-09-2019 and I placed an order for a McChicken delux and I receive a beef McFeast delux. I go to the teller to have it changed and she argues with me that I ordered the wrong meal. She calls the manager to change the meal and he tells me that he cannot change it as they don't sell chicken burgers. He refused to change the order. I also used my McDonalds app and redeemed the 2 Big Mac's @ R55. 2min lapses and the manager (Quiniso) states that there is a problem with the system and he cannot place the order. He also tells me that there is nothing that he can do to get the deal back on the app as the time to redeem have lapsed. He is the most useless manager that I have ever spoken to. His attitude as well as the staff working with with him stinks and this is the reason as to why I will never use this branch and will always choose McDonald's as the very last option. My order number was 267. I asked for a refund and left the store. Your staff needs a change in attitude and more training when it comes to customer service. I await your call.
