McDonalds sent me an email today about double cheeseburger for $0.50 if ordered through the App. I went to the App, which I had a little trouble navigating, and did nothing when I pressed VIEW DEAL on the $0.50 Double Cheeseburger Deal. This was quite troubling and looked very bad for McDonalds. I went to the restaurant to get my order and complain, but I realize that nobody there could help me, although they were all very nice to me as there was no other customers in there at that time.The food was excellent. I would advise you to improve on your App by testing it better and refunding me for the price of the double cheeseburger because I think this aggravation is worth much more than $0.50.
