McDonald's 4+

I have always been using the app to place my order but there’s 1 time where I ordered and upon reaching the outlet I was informed that there was a problem with their system and the order cannot be received although I have paid already. I was told to place another order manually and pay again and my previous order will be refunded. However, it’s been almost a month but no refund yet and I submitted a complaint via app and was emailed to provide few information which I did. However, there’s no respond anymore after that till today despite the few follow up emails that I sent. Appreciate a reply even if there’s no update yet so that I at least know that my case is being worked on.

My family and I went to McD drive thru today. When we ordered food from the store clerk, before we finished ordering, she spoke in a very unpleasant and impatient tone and asked us to go to the front to pay impatiently. The point is that we haven't finished ordering yet, and she was already very impatient while we were ordering. At that time, we had the sticker of mcd drive thru vip, so we asked her what we could get with that mcd drive thru vip, and she just ignored us. Then when we went to the counter, we asked again, she just stared at us and blamed us for not telling her earlier, but we told her early, and she acted like she didn't hear and showed us with a super super bad face. I'm very disappointed with the staff at this store. My family and I go there from time to time but we never meet this situation every time we go. This is the first time I've met this situation. I'm very disappointed at the same time I’m very angry hope you guys can improve the attitude of this kind of store clerk I don't want to be scolded by such a store clerk next time I go there, just wasting my time and ruining my good mood for the whole day😮‍💨

Need advice for my app/phone. I set my new iPhone as normal, downloaded apps I needed for daily use including the McDonald's app and everything just work fine. Then I decided to restore data from iOS backup. However, after completing this step, the McDonald's app now says "Oops! Something went wrong! DCH-NET-VAL-403-NON" when I wanted to open it. Tried reinstall the app, erase/resetting the phone to the factory state, changing the country and region and even tried restoring it with iTunes but still doesn't work. Asking my friends to try installing the same app on their iPhones of the same model as mine and with the same iOS version, the app worked perfectly. Any ideas why this happened?
