Disgusting service and dirty hotel

My family and I booked a room for 4 nights in this hotel so we got there around 5pm snd checked in on a Friday. We got the key and it looked busy given the time in which we took we decided to go up in to our room as it seemed like no one can help us with out bags which was fine because again it's busy and people are checking in. We go up on the lift and we walk around trying to find our room number but we couldn't it until we saw on the butlers (if that's the correct word for them) and he advised us to wait for him so we could escort us to our room and so we wait.A couple of mins later he comes out of the room and leads the way and on our way there I just remember us looking at each other like confused as to what's going on. We enter a place that's like the behind the hotel, we pass the kitchen and go into a lift and the whole time we are just confused at the condition of where we're walking and going to we get into the lift and still the condition of the place looks like it's not maintained well, it just looks like a old building. So finally we get to the room and we all just looked around and no one was happy about the room. We tried to switch the lights on but it was still dark, looked at the condition the room was in and it was just not what we expected especially because it wasn't our first time there and we knew we couldn't swap rooms because again the hotel is packed so there was no way do we called reception and asked them to come check out the lightning and the guy on the phone just said ok but nobody came so called again asking for the same thing and also asked for a iron and kettle and this time it was a lady and she also says ok. Then the butler comes through with just the kettle and we ask him for the other stuff,he says that he is coming back with the iron but he doesn't know anything about the lights. We call reception again and the person on the phone says and I quote "what do you want again?" "What else do you want?" So my sister answered and said the room is dark and they say ok. Then moments later someone from maintenance comes to check it out and he also confirms that it's dark and they weren't aware so he goes back and comes back and fixes it. This was just under an hour or 2 since check in and we're already and the condition of the room, the furniture is old, the head boards look like they're from 10+ years ago, the beds are rock solid-singles beds and the double beds are also uncomfortable and it like they have holes in the middle like they're uneven. Customer service is non existent, we have to ask for simple things like tissue on a daily basis, the people in reception are just not bothered and can't speak to customers at all, I work in a customer servicing sector so I know how a business is run especially if you're client facing. Customers need to keep calling for service is absolutely unacceptable and that wasn't enough the bathroom was disgusting, the shower is big but only 1 person can shower at a time because there's 1 shower head and 5ge water pressure is low but that's not the biggest issue, the shower is disgusting, it had moles showing that the place is not well kept and not cleaned at all and I even took pictures because I couldn't believe my eyes. Fungal infections are hard to treat, I know because I've had it and the medication is expensive so this hotel has basically showed that they don't care about hygiene, our health or wellbeing. I regret going there and hate that I paid money for such, I'm utterly disgusted in everything this hotel has to offer
