 USER: Hello, I am Sandra Nelson.

ASSISTANT: Hello Nelson, how can I render you today?

USER: I want to to cancel my trip due to some financial issues going on in my family. Can you aid me in cancelling my existing reservation?

ASSISTANT: Sure, we are rapturous to help you.

USER: Thank you. Before proceeding further, I have one doubt. If my ticket will be cancelled, how many days it takes to get the refund from the merchant?

ASSISTANT: Yes Nelson, it takes 3 to 4 working days.

USER: Ok, fine.

ASSISTANT: To proceed further, on whose name the ticket has been booked formerly?

USER: Yes, I have booked the ticket on my name itself.

ASSISTANT: Ok Nelson, hold on for a moment. Let me check in our records.

USER: Yes, take your time. I will be waiting for your response.

ASSISTANT: Sorry Nelson, there are no flights reserved on your name.

USER: That's ok. Yesterday, I tried to cancel my ticket, but I didn't get any confirmation message. I think it might have been cancelled successfully. I will check with my bank on my refund status.

ASSISTANT: Yes, it might be cancelled before. If your concern is not solved you can reach back to us.

USER: Sure, thank you for your support.

ASSISTANT: Welcome, thank you for opting us. Have a great day.

USER: You are welcome.
