I have a problem . What's the problem ? My mattress was supposed to be delivered today . Is there a problem ? The delivery people showed up four hours late . I apologize for their tardiness . I was late for work because of them . Again , I do apologize for the inconvenience . I want my money back for the delivery . Seeing as they were late , that won't be a problem . It shouldn't be a problem . I'm going to refund your money right now .
A:
No
