Thank you for your email.
All final audited f/s were sent to your accounting staff and they confirmed back to us that they agreed and number were correct. In this case, it is seemed to me that they did not check tax number.
You have revised tax number several times and that's why we sent final audited f/s for your confirmation. As on my hand now, your TB excel file that we confirm with your staff, your tax number is 552,922.16. (I don't have your file >"PND 50 adj. sale Inventories"). Pls confirm again that this number is correct.
