A、Transfer the money to the man as soon as possible. B、Try to sort out the truth and call the bank. C、Check the account number w

W：Well, Mr. Smith, I’ve looked into your invoice and found out why it hasn’t been paid.
M：Why?
W：We asked our bank to transfer the money but they couldn’t. They said that your bank details were wrong. So they couldn’t transfer the money then.
M：What do you mean my bank details were wrong? They are printed on our invoice. I think that you receive the same invoice as all our 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...
M：Hold on. Did you say the Bank of Scotland?
W：Yes. What’s the matter?
M：It is the Royal Bank of Scotland, not the Bank of Scotland.
W：You mean there are two different banks?
M：Exactly.
W：OK, Mr. Smith. 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’ve sorted it out.
