I have been trying to explain to you for these things that I booked for you: A car with a driver to Ha Giang for 4d3n, with the price is $320.
Frist of all, you would never find any service with such a price.
Second, with the attitude of the driver, are you sure he was that bad? I had some photos of you guys with him and you both seems very happy. And also, do you think that if you were nice to him, then would he react like that?
Third: About the food price: this is a free and easy trip, you eat what you pay for, and the price I estimated to you were just estimated. I didn't book a tour for you, please make it clear. A common private tour to Ha Giang would cost you no less than $300 per person.
Such a pity that Airbnb doesn't support for posting photos on reviews, otherwise, I have a bunch photos of you guys with the driver and you seems very happy.
Good luck with your next trip!
