The Park Hotel — Hammering at room above me at night

I am writing this mail from the room no 235 of park hotel at around 1 AM in night. I had booked my stay at the hotel @ the park, kolkata for 2 nights along with my friend for 12th Feb to 14th Feb 2023. I was given room no 235.
The first night, that’s 12th was ok but the next nights that is 13th night is going horrible for me. It seems that few rooms in the hotel are under renovation. There is continuous hammering in the room above me. I called reception 5 times but the hammering did not stop. Now since I m a patient of high blood pressure, I m feeling very uneasy, very restless & very disturbed mentally due to being intolerant hammering. If any thing happens to my health, u guys will be completely liable & responsible for the same. I m going to take this matter to highest authority of the country. We don’t pay such a large amount for this kind of service.
