Complete utter mess. You cannot contact anyone for help. The payment information incorrectly will not allow for the addition of any credit card. I've called AMEX, Visa and Mastercard. All if stated it's a problem with the McDonald's app. So, I go to Burger King, Jack in the Box, Taco Bell , Carl's Jr and every other competitor who has a operating app and great customer support. In addition, any competitors rewards program is better than McDonald's. Good like trying to use a reward...joke!
