Hi. I am Alexander Gonzalez.
Hello, how may I be of your service?
Actually I made a earlier reservation to go for a trip with my friends, but heavy work load in office I want to change my reservation. Can you help me?
Sure, give me sometime. I will check and get back to you.
Ok.
Thank you for waiting. Unfortunately there is no reservation found matching your name.
No issue, I will choose other alternative.
Thank you for reaching us.
