Terrible Service

16 July 2018 we purchased 2 veggie burger meals from the McDonalds Retail Crossing. We used the drive through. My husband clearly told the person taking the order that both burgers should not have sauce and 1 should have sauce. We even requested the special from the app. The superviosor incharge told us that we need to go into the store to activate the special yet on the app it states that you can activate it using the drive through as well. When we returned home we discovered that both the burgers had sauce. My husband immediately called the store and spoke to Slone who said theres nothing she can do and we would need to drive back to the store to get the meal replaced. We placed an order made a simple request and it was still wrong and on to of in order to get the proper order and wait more yet again we would have needed to use our petrol and go back to the store - this isnt the first time we received service like this. I want my order replaced in full!!!
