Hi.
Hello. How glad that I can assist you?
I need to change my existing reservation, can you please help me with that?
Sure, I can help you. Can I know your name for checking in our previous booking list?
Ryan Collins here.
Please give me a moment.
Sure.
Thank you for being on hold, I have checked with your information in my portal to change your booking but it is displayed that there is no user name found to change it.
Ok, no problem. Thanks for your information.
You are welcome and have a nice day.
