Manyo Hotel and Resort

There was no hot water in the morning, and when I returned that evening there still wasn't any. The front desk said the whole hotel was affected and it couldn't be fixed that day. About 15 minutes later, they said it was fixed and showed me water in another room that wasn't cold. They told me to let my room's water run for around 10 minutes. I asked if they could run a tap in another vacant room or the restroom by the front desk to clear the cold water faster. The staff member in brown said he didn't have authority to do that. While talking to the staff member in white, I went back to my room because I didn't have my key. I had to return again because my phone battery was at zero. I asked the staff member in brown if the lukewarm water was as hot as it got, and he said the manager set the temperature. I ran the water for about 10 minutes, but it was still cold, so I went back to the desk. The earlier staff had left and there was a new employee. At around 10:23 p.m. I told him the water was still cold after running it for 10 minutes. He replied that he'd started his shift at 10:00 p.m. Why tell me that? I was speaking to the hotel's front desk about an unresolved room problem, not to him personally. He also said the CCTV was working and that I'd been coming to the front desk frequently. I only went there because the room issue hadn't been fixed, and I returned to my room when I realized I'd forgotten my things. Is it wrong to go to reception when there's a problem with the room? I wasn't asking for anything unreasonable or asking them to raise the maximum temperature, since the staff member in brown had already said the manager set it. I was simply saying only cold water came out. I won't return after checking out, and I won't recommend this hotel to people I know.
