Dear Mr. Jeff,
We've already received the telegraphic transfer of ￥10,000 on March 25th, 2011.However,I am afraid that you have neglected something, that's the cost of freight and insurance that was indicated on the invoice we faxed to you.
We would therefore like to ask you to transfer an additional ￥800 so that we can arrange the shipment the soonest possible.
We are going to deliver you the goods immediately after we receive the full payment.
I'm sorry to admit that I just forgot the cost of freight and insurance, as I've been so busy these days. I will transfer an additional RMB 800 right away. Please check.
Reading your e-mail, I feel quite sorry for my oversight. I shouldn't have forgotten the cost of insurance and freight. Now I will deliver you the money through the bank transfer, please check and confirm it once the money arrive.
