I ordered and paid through the mobile app

I ordered and paid through the mobile app. It was a large order - dinner for 3 people - just over$46. When I arrived, the worker told me they did not have potato wedges in stock, nor the chicken bowls. I asked why the app let me order it and she said she doesn't use the app. They also forgot a doughnut from the order and gave me an entirely different doughnut, in place of the wedges. The manager told me that was all he could do. Ridiculous. One doughnut does not equal the $6 I paid for the 2 wedges. Horrendous customer service. In order for everyone to have the dinner they wanted, I had to go to another Tims location & buy the missing items. So I paid twice. Never again. The food wasn't even good & it was cold.
