Society Harassment

I moved into a new society on rent in the month of March 2020 and at that time i could not install the AC since i was busy settling the stuffs in the new house and then the lock down started on account of Covid-19. I thought, i'll install the AC once the lock down is over but the dates have been extended a couple of time now. I have a heart patient (Dad) and a diabetic patient (Mom) in my house who started complaining of extreme heat and sweat and that they are unable to get sleep. Hence, i approached one of the society member and said, that i do understand that Mumbai is under lock down but did explain him the situation in my house and asked if we could get the permission to get the AC installed. he advised me to talk to my owner and ask him to drop an email to the society. One the email is come then the society will allow you to install the AC. Once the owner confirmed that he already sent the email, i again spoke to society member and he started saying that we cannot give the permission as we cannot take a risk of allowing an outsider at this point of time. So, i asked him if the vegetable vendors, fruit and cold storage vendors can be allowed in the premise then why is it so difficult to allow a single technician to install the AC in our house. The risk is everywhere and in fact the risk in allowing the technician would be less since he will hardly take 2 hours to complete the work. Upon hearing everything they started saying you cannot talk to me about this and you will have to talk to your owner. I explained everything to the owner including my parents heath condition but he is saying that he cannot do anything on this since we or the society cannot take a risk here. When asked if anything happens to my parents because of severe heat then will the society or you will be answerable for it and he was very upfront and rude to say why will be take the responsibility. We will have to abide the government rule. I didn't say anything and hung up the phone. The very next day, a saw a couple of workers in the society behind my washroom area and was terrified by this. When i asked them who gave the permission to come near my washroom without asking us then they said that we had to take some stuff from here which we had left at the time of construction and now we need it since we need to fix some leakage issue in one of the flats. I again spoke to the society members and the owner that if these people can be allowed then why can't a single technician can be allowed. I am ready to the responsibility if anything goes wrong as well. they still denied permission. Now, i see more workers in the society and when asked they informed that we are going to start the construction work again and we have been given permission by the society. This time again when I asked the society how come these permissions are given. They said that the society has the permission from BMC. Not sure, how i can get a permission to install an AC in my flat. Need Help.
