Input: F: Hello, Benson Software, you're through to customer service. ,M: Hello, this is Mike Williams from Smiths retailers. I'm phoning about the CD players you sent last week. Emm, I'm afraid you don't seem to have sent us enough. ,F: Oh, dear, I'm sorry about that. How many did you receive? ,M: Well, we received 50, but I'm pretty sure we ordered 150. ,F: Just a moment, I'll check your order. Well, according to our records, you seem to have ordered 50. ,M: Really? Oh, perhaps there's been a mistake. I feel certain we have ordered 150. ,F: Sorry about the misunderstanding. We'll get the extra 100 to you as soon as possible.
(A) M: Don't count wrong again. I received none, so it should be 50 this time. (B) M: 150 CD players, yes. I've got 20 before, so it'll be 150 more this time. (C) M: I didn’t hear you. Please could you tell me again? (D) M: Great. Then I will be expecting for the rest 100 CD players. Thanks.
