Holiday Inn Express CHENGDU TIANFU AIRPORT ZONE, an IHG Hotel

I stayed at a hotel on a cold day, and when I complained because the room was cold, they said the main heater was broken and they were fixing it and there was no heater. I had no choice but to endure it, but it was too cold... I checked that there was a room in another hotel right next door, and it was warm, so I paid more and tried to move, but the heater stopped working an hour after I checked in, and it was too cold and I said I would check out, and only then did they say the heater was working and send someone to turn it up! I wasn't the only one who heard it, and I clearly said that the main heater was broken and the entire room wasn't heated, but another employee said it was working and sent someone to turn it up? I saw another foreign woman complaining because she was cold and really angry!! It's a hotel that many foreigners visit, so you shouldn't lie and save on utility costs!! I don't want to go there again! There's a Chinese hotel in the next door, and I highly recommend it! When I asked if there was a warm room, they brought me warm tea and kindly showed me the room!
