The landlord wants the OP out in one month, which they are legally entitled to do. The OP says they want to stay for three months rather than one. The landlord says OK but the rent will be $400 per month more. The OP says fuck you and I'm not paying rent anymore and take it out of my $12000 deposit. The landlord cuts the electricity. Is this an accurate summary of the situation?
I would not want a tenant like you. Correct the LL should not have cut your electricity, But you instigated it and it's your own bloody fault! You cannot demand to stay until July, he has the legal right for you to leave in one month. You broke the law first, he broke it second. For $400 a month you could have stayed until July as you wanted but now you have created your own mess and you are going to have to deal with the stress sorting it out, no lights and aircon in the mean time. The weathers warming up a bit these days, isn't it? Good luck.
