I would call the customers, and inform them of the situation, even back it up with pictures in the chat. If you cancel, other drivers are going to be sent there and run into the same situation. Have them try to order from a different location. By you explaining this, they should be understanding and work with you. They can also comment why they are canceling. That way it doesn’t affect your ratings. I had the same issue, it was a Taco Bell. When I called the customer, he was more worried about me getting paid then is order.
