Please be advised that we all (including our QA/QC) are not allowed to sign on COA too. Kindly you emphasize your Document and LSC team NOT to sign on COA as well. If there is any instruction of COA signed, please keep CSR/order handler that we cannot comply or escalate to in charge IES for further help.
Please cascade this communication down to your Document and LSC team with verbal explanation to ensure that your team understand well and follow. If you have any question, please feel free to ask us. Thank you in advance for your kind cooperation.
