Maneetel Krabi Beachfront in Ao Nang

We booked a night here from October 15 to 16 in the most expensive room, with the aim of enjoying the jacuzzi with a view of the beach. As soon as we arrived at the room, we turned on the jacuzzi, when to our surprise, a lot of trash started coming out of the drain, making the water dirty. We emptied it and refilled it, and the situation repeated itself. We went to the hotel reception, who sent a man to resolve the situation. The man stood there for about 15-20 minutes just looking at the jacuzzi running and said he would be back in 10 minutes and to leave the jacuzzi running. We waited almost an hour and a half and no one showed up. We went back to reception and asked for a solution, since the purpose of our stay here had not been fulfilled, and they told us to wait until the next morning to speak to the manager. In the next morning we went back to reception and they told us that the manager was not there and that we would have to send an email. Of course i had no answer yet.
We paid twice the price of the other rooms, for something specific that we cannot use. the room is not in good condition (there was even water on the floor coming from who knows where).
