As per record, we have booked a connected room with River View for 1 double bed & 2 single beds for 3 nights. Upon arrival at the checked in counter, the staff by the name of Maria straight away offered us an upgrade of the connected room for the 2nd & 3rd night at the upper floor with a better view. But 1st night we have to stay at lower flr in a big room with 1 double bed & 2 single bed. We said OK and she checked us into Room 206. When we got to the room, we rest for a bit before we really check out the room. But my son was complaining about the room. Being the room are like an extended room for the room flr are build by wood and noisy when u walk. No centralised aircond but a split unit aircon which is not cold. Mattress are hard as if it's already more than 10years old. This room gave us a feeling as if we are some illegal immigrant. We went back to Trip.com to check the review and we found few customers are having the same experience. I've screenshot 1 of them and attached as photo. We went down to complaint & demanded change room to the room we booked in advance. And it's not our problem that they over sold their rooms & neglected customers who booked & pay in advance. Till the end, we get the room we booked but Maria claimed its VIP room which this room fits the description of the room we book. On the day we chevked out, Maria was on duty. Very bad attitude. No eye contact, no greetings, no thank you. She don't deserve to be assigned at the front desk.
