We booked hotel and told them when we will arrive in Hanoi so that they can pick us up. They did not come to airport as they said they would. We called and texted them 20 times in 4 hours and they did not pick up phone. And no taxis knew where they were. So we stayed at a different hotel. They finally sent us text saying we would not be charged. Then they sent another text letting us know they will charge us and if we did not like it, we should complain to Expedia. They are VERY unprofessional, dishonest, unethical. I would recommend that you not do business with these scammers
