Dear Khun June,
According to the RMA for PO# 1110099757 has been done and you has already get the CN but the replacement PO was cancelled as per the 15 days policy.
You are able to submit a new PO number but remember to quote this is a replacement PO for PO# 1110099757 and the replacement PO# 1110101607 has been changed to PO# xxxxxxxxxx due to cancellation for more than 15 days.
Dear Khun Yai,
This case need you to upload a note in the RAR form to say that replacement PO# 1110101607 has been changed to PO# xxxxxxxx due to cancellation for more than 15 days. Otherwise we may not be able to track back in the future.
