Hello
Hello, how can I help?
I want to schedule an apartment viewing at North Hill Apartments for Friday at 7 pm. 
Could you give me your name, please?
My name is John. I have just realized I have an interview on Friday at 7pm
Have you already paid the application fee for the apartment?
Does the apartment have CCTV cameras?
No CCTV cameras, do you have another time you want to book for?
I can not remember if I have payed the application fee. Make the viewing to be on Saturday 7PM
I can mark you as unpaid for now, will that work?
That works for me
Saturday at 4pm is available, would you like to book that instead?
Yes thanks. 
Excellent, the viewing is scheduled now!
Thanks for your help. Have a great day
Thank you and goodbye.
