We operate a construction company in Zambia and have recently been dealing with a couple of companies in China. The one company that we have dealt with for the first time is giving us problems.

We ordered the machinery and were instructed to transfer the funds in the bank account whose details we were provided with. However, as soon as the transfer was made, we immediately received an e-mail with the ''now'' correct bank account details. Apperently the bank account details we were given initially were incorrect (one incorrect digit on the account number). However, the rest of the bank details were the same.

The are failing to locate the funds and have been advised by the chinese company that they have reported the matter to the police in China who are investigating. The investigation outcome or the claim so far is that our e-mail account was hacked into as the IP adresses shown on some of ''our'' e-mails received by the company ogirinated from other countries. However, I think this is not true since the police should have started thier investigations from the bank where the funds were trasfered. May someone please advise me which independent authorities I can report to that will carry out the investigations. Or is there a body of the WTO that deal with such fruad in international trade.
