Hello

I need help. I had some business person come to Korea to purchase some items - to be precise shoes in bulk. He stuffed a container full of them. Too bad upon reaching his country, he learnt that quite a number were damaged and wrongly paired rendering them useless. 

A korean friend is the one who introduced me to the suppliers. Now when I call him to claim for the spoilt shoes, all he tells me is that the supplier no longer picks up his phone which to me sounds a little bit weird owing to the fact that before, he had direct link to them. 

We feel cheated in the deal and really need a refund for the bad shoes. Please advise me on how to go about the issue. The businessman is currently not around but I feel oblidged to follow it up for him owing to the fact that I was the one who introduced them.

Any help in this regard will be highly appreciated.

Thank you in advance
