Due to conversation Aor and Elin about add comment root cause on "CS did not provide appropriate answer/solution". Then I would like to request a additional box in complaint tracking form for QA to comment the reason or root cause of inappropriate answer form agent. You may use "Comment form QA/ คำแนะนำจากQA" as it name. Or is it possible to use "Comments / คำแนะนำอื่นๆ" instead to make it easier and tidy?
