Even though I booked the room several weeks in advance, when I went to check in, even though I arrived almost 2 hours before check-in time, there was no staff there. I thought it was because I arrived too early, so I went to eat and came back but there was still no one there. When it was almost time to check in, the staff came back and apologized because they had to run alternately to 2 branches, so I sympathized and waited. A while later, they called me back and said that the housekeeping system in my room had an error and was being fixed, so they were arranging another room for me, so they asked me to wait longer (at this time, it was already late for check-in). A while later, they called me back and said that the room I booked had been canceled and the reason I didn't receive the cancellation email was because a staff member forgot to send me the cancellation email :) The solution was that this hotel would introduce me to another hotel in District 5, which is further away, because District 1 and District 3 are now fully booked (I was afraid because I had just booked in advance and it happened again). Because I also contacted many hotels nearby but they were all full, so I had no choice but to agree to stay at the hotel recommended in District 5. Next was the money issue. The hotel asked me to cancel on the app so the money would be returned to my account, but because I was late for check-in, no app would allow me to cancel. After a long time, the hotel said they would pay me in cash equal to the amount the hotel received, but that amount was smaller than the amount I paid on the app because the reason was that the balance was the commission the app received, so the hotel was not responsible for paying the full amount I paid :). I never booked a hotel in advance, spent money to book a taxi from the bus station to the hotel, and then arrived earlier than the check-in time. Now the room was canceled, I was tired, did not get a full refund, and had to spend more money to book a taxi to the hotel in District 5. I do not agree with not getting the full money back and that is not my fault because I have suffered a lot. For a long time, after many solutions, the staff had to take money from their own pocket and give it to me, ask for contact information and ask me to contact the staff and the app to cancel (very time-consuming) so I could get the money back through the app and I would pay the money I received. The staff tried to support but could not win over the hotel owner, I tried very hard to get the full money! There are many things but not enough to write, SO BAD AND STILL PROVIDING SERVICE!
