Dear Eric,
I am so sorry for any inconvenience caused during this time, but let me clarify this situation please:
• Chuong asked IT to upload amount as in his confirmation on 08.01.16 (2725usd at this time)
• He confirmed booking to Agent on 08.1.16, later on 12.01 TO changed some services and he sent an email to customer service to ask for postpone the invoice issuance and will update the amount later.
• Now clients finalize with amount 2,610 usd which they are correct in TP & NS => actually this amount had been uploaded after Chuong corrected from 2725usd to 2610usd and luckily it’s correct.
I am sure that my team only asks IT to upload the booking to NS and only asks your team to issue invoice when the booking is confirmed, as I remind them oftently .
For this case, I think there was only thing that your team missed information from the email Chuong sent on 12.01.16, I can understand how busy your team are, but we should find a solution for this issue to avoid getting similar cases in the future as we will have many many changes like this during trip of one booking.
Thank you and best regards,
Thi
