Dear Rony,
Sorry for the late update to you.
After we have received your letter and we were getting ready to send it to Dilaki. We think about whether this letter should be signed by Khun Thirawit as the Senior Executive Vice President of DA1991. Thus, we have revised the content of signing part and slight changed to some content mentioned therein.
Furthermore, according to our company policy, we will not sign any document in a foreign language except Thai and English but we still need your help to provide Spanish translation of the attached revised letter. In the meantime, we just send such letter to Khun Thirawit for signing.
Thank you very much for your support and sorry for the inconvenience to you.
Best regards,
