Dear Khun Chanisara,
Thank you for the quotation, however we send those chocolate fountain many time before and it always come back, working for 1 week and broken down again, even some do not work after get back to our hotel.
I believe that at least service should be free of charge as we never had those fountain fix correctly. Please void 800 baht X2.
If you have any inquiries please feel free to let me know
