Hello.
Hello, how may I help you for the day?
I am Carol Collins. Due to my health problem I want to change my reservation, can you please help me to change my reservation?
Ok, please hold on for a moment till I check with availability.
Sure, take your own time.
I'm so sorry to inform you, but there is no active reservation in our data base.
That's fine. Thank you for your service.
Thank you for consulting with our services. Have a great day ahead.
