Tonight we had a problem with our mobile order not going through. It wasn't in the system at Taco Bell but the charge was pending on my account. After trying to figure out what happened it appeared that the order was somehow voided. It was a problem with the app and wasn't the fault of any of the Taco Bell employees but the manager working still apologized and gave us our food at no charge even after we insisted on paying. She is awesome and everyone there was very accommodating and helpful.
