Landlord threatening to cut off water supply and denying entry to guests

Hi, Can a landlord deny water supply? Can they also deny entry to short term guests? Also, what to do if landlord threatening to vacate the property only after 20 days of possession and denying to reimburse the security deposit? - as per agreement 6 months no security imbursement clause is added. But since the landlord wants me out.. Is that valid? - no clause in the agreement for inviting and keeping guests. - I am paying 300 for water and 500 maintenance and yet the person is denying me enough water saying '300 rupay mai kitna pani milta hai?' they won't fill the tanks until completely empty and thus making us call them every time we are out of water. They threatened me of cutting the water supply and talking trash about my character because I invited friends over for stay. Asked me to leave immediately and even threatened me when I said I'm going to file a police complaint. I have a recording of the conversation as well where the landlord misbehaved with me on call, calling my character bad and that he won't allow entry at night. There is no such clause in the agreement mentioning these things.
