Tim Hortons

On my way to work this morning I ordered a blueberry doughnut and latte. Arrived at work with a coffee with milk and a blueberry muffin. Totally got my order wrong. Couldn't take it back as was working a twelve hour shift. Very frustrating! What should I do to resolve this and either get my money back or a coupon for the right order. As well they repeat the order so how could it be so wrong! A very upset customer
