Hello. Mark Garcia here.
Hello Mark, how may I assist you?
I would like to change my current reservation. Can you please help me out?
Sure, I will help you. Please be on hold, let me check your reservation status in our database.
Ok, please check and inform my reservation status.
Sorry Mark, I have not found any reservation under your name in our database.
