Hello.
Hello, how may I help you?
I want to change my reservation, because I have another important meetings on those dates so can you please change my reservation?
Ok, give me your name to check with your reservation status.
Sure, my name is Betty Collins.
Wait for a while.

Oh! it's ok no problem.

It's ok.
Have a nice day.
