Hi.
Hello, How can I render you today?
 I made a reservation earlier this week to give a seminar but due to weather conditions I need to change the reservation dates.
Ok.
Will you be my helping hand in changing my reservation with the name of Linda Roberts?
Sure, we are here to aid you.
Thank you.
Please, stay online I will check with the reservation and revert to you.
Ok.
Thanks for your time.
Fine.
We could not find any reservation with your name Linda Roberts.
No worries at all.
Thank you for reaching us.
