fish? DOA

[pipsqueakz]

So today I sold 3 fish from my pond. They were all very healthy. This guy comes to pick them up and I've just had an email saying one died on way home. What do I do?? As I say they were healthy and OK in my pond is he trying to pull a fast one to get a refund? How can he prove its dead his for I deal with this???
