Hi. I am Margaret Perez.
Hello, what service are you looking for?
I have to change my previous flight ticket reservation, can you please me in that one?
Sure, please wait while I look for your reservation in our system.
Thank you and I can wait for your response.
We didn't find any reservation on your name.
Ok, no issues with that one. Thank you for your immediate response and providing the information.
Thank you.
