Hello.
Hello. How may I help you out?
I made a reservation earlier to attend a get together party with my college friends. Due to some issues in college it  got postponed, will you help me in changing the previous reservation?
Sure, I will help you in changing the ticket.
Thank you for accepting my request.
Sorry, there are no reservations found.
Ok, not an issue. Myself Deborah Martin.
Thank you for reaching us.
