Dear Mr. Tippawan,
Good afternoon.
Sorry for all the delays, since we had some days' holidays for Chinese New Year,
only came back to work today.
The test report will be submitted to you by tomorrow.
And, have you received the new bolts? they were sent to you two weeks ago to replace the old bolts.
Again, I have to apologize for all the delays and troubles caused by the bolts.
I will submit the report to you timely tomorrow.
Best wishes!
