I have sent by DHL courier some admission documents to your office directly on Monday. I believe it included theirs. Please forward it to the exhibitor directly after making a copy for your files. I was rushing to send it off to you that I did not make a copy for my file.
I am not sure what you wrote in your email to the company but this is only the first week of August. Can they not be a little patient? It takes time for post to reach Germany to Thailand. I mean did they have to write 3 emails over 2 days?
Attached please find the information usually sent with the admission documents.
