Burger King - Ravenswood and blaming Mr D for bad service

I visited Burger King in Ravenswood, Boksburg. On the 6th of May I sent a complaint to customer care. I received a response of Burger King blaming Mr Delivery for what happened. I responded, asking them how they can blame Mr D for their poor service and poor food and still today, still no response. Please see email that I sent, with no refund for my order or any type of helpful response:

Burger King in Ravenswood is completely useless. I used Mr Delivery to place an order and selected collection. When I arrived at Burger King to collect, I wasn't allowed to go inside to collect my order. I had to wait in the queue for more than 20 mins, with only 3 cars in front of me, just to be told at at window that the food hasn't even been prepared yet. All the app did was eliminate the paying process.

The very few times I go to Ravenswood Burger King, the order is either incorrect or we have to pull over into the parking lot to wait. How is it that you're capable of messing up every order with very limited amount of customers? It's bad enough making us wait 30+ mins for below average food, at least make sure you're prepared when ordering via the app.

I want a refund for my entire order. D***

I have never experienced an issue when ordering via the Mr D app.
