Dear Khun Supachai,
Greetings from The Seasons Bangkok Huamark !
First of all, thank you very much for giving me a chance to talk to you on the phone earlier and I would like to express my sincerest apologies for the incident once again.
I have attached the apology letter from Khun Ivor Rai, Executive General Manager to you with the updated invoice of the group arrival’s today as per discussion.
Thank you very much for your kind support and attention. Please feel free to contact me at all time for any further inquiries you may have.
