After go through the details, may some misunderstood and unclear of transaction during 1st batch of cylinders. The invoice WP-01-2013 should be cancelled and total deducted amount (690,200Baht) will pay back to you .
Anyway, because of our manager whose in charge on this had already went back to Japan. So, may I request some correspondence about the payment of $81,740 to Wipro for cylinders modification. Because this amount may relate to freight and handling charge of 690,200 Baht. Could you please help to find out the evidence to close this issued
