Your organization provides travel assistance for business customers. A regular customer requested that $1,000 in cash and a visa be ready for pick-up at the information desk at the local airport for one of their sales representatives flying out for an important meeting in New York.

When the customer presented themselves at the desk at 0400, the visa was correct, but the envelope contained €1,000, not

$1,000. He was forced to change the currency at the airport at a very poor rate of exchange and he nearly missed his flight. The business customer has just sent you a complaint outlining the problem by email.

Your task: Write an email to the customer apologizing for the mix up and assuring them that this was a one-off incident.
