W: Well, Mr. Smith, I’ve looked into your invoice and found out why it hasn’t been paid.
M: Why?

M: What do you mean by "my bank details were wrong"? They are printed on our invoice. I think that you receive the same invoice as all our other customers. But we did receive the money from the other customers.
W: I’m sorry. What did you say?
M: I said our bank details were printed on the invoice.
W: Well, I have the invoice here. Can we just check? The account number is 21406881. Is that right?
M: Yes, that’s right. And what about the name of the bank?
W: At the Bank of Scotland at 46 Portland Street in...

W: You mean there are two different banks?
M: Exactly.
W: OK, Mr. Smith.(14)I’ll ask our bank to transfer the amount to the Royal Bank of Scotland as soon as it opens. I’m sorry about the mistake.
M: Well, I’m glad we sort it out.
