House owner is not returning back my security deposit amount

Before marriage My husband took a house for rent with proper rental agreement with his name. After that, he was paying rent regularly to every month without fail but no rent receipt has been given. After 3 months he got married(its me) and he was introduced me to that house owner. At that time they said ok happy for you. After I went there. They are making water issues. we went and asked about this issue. He said that we are giving a house for one person and you and your wife is staying here. so please vacate immediately. we asked 3 months notice period as said in the agreement. but they wont allow to stay there. we asked one month notice period at least. they said ok. and after 2 days we got a new house for rent. we informed and we are planned to vacate at end of the month. he said ok and he asked 2 month rent and painting charges and water bill and EB bill also. So he is planning to deduct amount of 30000 from 50000. But actually we have to pay one month rent, painting charge, water bill and EB bill as well. In that situation we argued with them but they wont listen and torturing us like no water supply and no power. then we decided to vacate one week before. we informed also. At last vacating day morning they are making issues again like water and all. we asked money but they said I wont give you, go and do anything. 2 days back we were vacated. but the house keys and the original agreement also is in with us. we are not given back to them. Please guide me in this situation what to do. Is anything problem to us or to them. Note: Now my husband is in depression because of this issue not for money they cheated us so. they are used our innocence.
