Hello,.
Hello, How exactly I can serve you the best today?
Please change my reservation, which is reserved earlier on my name Andrew Gonzalez. As my friend birthday party place has been changed.
Sure, we are perky to serve you.
Thank you.
Please wait for a while, to check the present status of your earlier reservation and let you know.
Sure.
Thank you for waiting.
My pleasure.
 I have checked in reservation list to change your ticket, but could not find any reservation with your name.
No problem at all.
Thank you for approaching us.
