Hello.
Hello, do you need any help from us?
I want to do some changes in my existing reservation. Can you help me for that?
Sure, could I have your name please?
My name is Anna Roberts.
Ok, please allow me a moment.
Sure, I will wait for your response.
Sorry, there is no reservation with your name in our portal to make changes.
That's ok, thank you for checking.
