Hello.
Hello. May I know what kind of service you are looking for?
  Would it be possible to change my reservation, which I have done with my name?
Sure, I can change your reservation right now. Before that I need to know your good name please?
My name is Deborah Parker.
Ok, Please allow me a moment to check for the previous reservation in our data base.
Ok, take your time.
