How about the repair fee?
It's for free, because your computers are still in the period of guarantee--two years.
Great! When can your technicians come to our factory?
They are working in another factory to provide maintenance right now. Let me call them and see whether they have solved the problem. Please wait a moment.
I've just contacted our technicians. They say they can go to your factory tomorrow afternoon. Can you tell me your factory's address, so they can find you easier?
That's wonderful. I appreciate your efficiency and cooperation.
To provide the As excellent after-sales service is our motto. Please wait for our maintenance staff in your factory tomorrow afternoon. They will be there on time.
Thank you again!
