听力每日练习 listen 2783 A new supplier

1-- Hi Steve. What do you think of the new supplier?
 
2-- We haven't had any problems so far. They offer a 24-hour technical back-up service. We've called them in three times this month. They always arrive within a couple of hours.
 
1--That's good service. Do we have to pay extra for that?
 
2--No. There's no call-out fee. It's included in the annual service contract.
