Where does Mike Lee work?

Hello, Ms. Brown, my name is Mike Lee and I’m calling from Burma Airways London office about your missing baggage. I just want to let you know that we have located the whereabouts of your lost baggage, and we can have it delivered to your house tomorrow. Or if you prefer, you can come into our office at the airport anytime between 9:00 a.m. and 6:00 p.m. to pick it up. Could you please contact me at 777-2213, during office hours today? Please let us know as soon as possible, so that we can make the best arrangement for you. And please accept our apologies for the mix-up.
