Geyser.

Early last week I told the Building Manager about my geyser as my water was/is not getting warm even if the geyser is on. He installed a new thermostat and the next day my water was warm, then the following days the same issue happened again and I called him and he came to check it then it was fine for that day. My issue is that my geyser seems to be on a timer, the water gets hot at 7:00am and I leave at 7:30 am (This never used to happen) during the day the water is warm but when I have to bath for work I don't have warm water. I have flu and again today I had to bath with cold water this morning.This is my second week dealing with this, I would appreciate it if this issue can get sorted out today as I can not be dealing with this again tomorrow. I am tired of always calling the Building Manager about this.
