Hello, Paul Taylor here.
Hello, Taylor. How can I help you?
 I need to do some updates in my existing reservation, as my friends have already booked my ticket in another flight along with theirs for a trip, I was not aware of this thing, can you please make some changes in the existing ticket for me?
Yes, please hold on for few seconds, I will go through your reservation details to do modifications in that.
Ok, thank you for your response, I will be on line.
But, there is no details recorded on your reservation in our database to do changes.
No issues, thank you for giving clarification.
Do you need anything else from us to help you?
No thanks.
Fine, thank you for choosing us.
You are welcome.
Have a great day.
