Staff don't know how to handle app orders

I have used the Mac Donald's app many times and with great success through the drive through and in the store. Unfortunately I decided today to use the Mac Donald's at Centurion life style center. I redeemed four different deals. I was told that I could only take one item by Norma at the drive through. I explained I have used the app more than once at the drive through and redeemed more than one item as other MacDonald s. She then screamed for her manager. She then told me I did not redeem the deal. I had to show her I redeemed the deal . She then asked where is the time where it's counting I showed her. I was then told her manager said I can take only one deal. I showed her the app allows me to choose different deals and I have done it before. She continues to argue with me . With the manager screaming one deal from the front of the store. Then I said I will lay a complaint as I know I can take more than one deal and I have done it before. This whole argument took more than 5 Minutes. In that time they could have taken my order. The manager then tells to come into the store with my three kids she will then look on the system for the deals. I was like you told me you can't do it . Now you can. She says it will take time come inside. By this time my kids are upset. And I am like the time you took arguing with me why did you not take my order. I had to leave and go to another take out. I could not redeem the deal at mac Donald's , which knew what to do, because I redeemed. The deal already. It was extremely upsetting experience. With the manager and the lady taking my order (Norma), Arguing with me . With all the time they spent arguing with me the could have taken my order.
