The hotel water pipe is broken, so there can't be hot water. How to complain?

If the hotel water pipe is broken, you can't use hot water. First of all, you should contact the room service department to explain the situation and ask them to contact the maintenance personnel of the engineering department for maintenance. Or contact the front desk and ask them for help.

If you are not sure, please don't repair it yourself, so as to avoid danger or worsen the situation and cause unnecessary trouble. You can also negotiate with the hotel to change rooms.
