M: Customer Service. Anthony Grant speaking. How may I help you?
W: I can't believe this is happening. I called and ordered a 32-inch bag last Friday. But today I found that you sent a 24-inch one. I'm planning to use that bag during our vacation in Mexico. But it doesn't seem possible any more, because we'll take off on Saturday. It's only 2 days away. What am I supposed to do?
M: I'm really sorry, madam. I'll check right away. Would you please tell me your order number?
W: It's CE2938.
M: Just a minute. I do apologize, madam. There did seem to be a mistake. I'll have the correct size bag sent to you by overnight mail right away. It will arrive in time for your Saturday trip. Again I apologize for any inconvenience caused by our mistake. I promise it won't happen again.
W: OK, well. Thank you.
M: Thank you, madam, for choosing Lynch Mail. I hope you have a wonderful vacation.
