If you are not able to bear the additional expenses in the name of hike in rental amount, you remain silent without taking any action on the basis of your earlier request to extend the tenancy.
Let the landlord send a notice, you give a reply notice and file a caveat petition before the jurisdictional court which is valid for three months, hence the landlord cannot get an exparte injunction agaisnt you nor he can be able to vacate you immediately.
If the landlord refuses to accept the monthly rent, you may send it by money order to his address. Let him return the money order with reason refusing to accept the same, you can issue a legal notice to him asking him to furnish his bank account details to which you can directly transfer the rental amount.
If he is not furnishing or refusing to this option also, then you may file a petition before the rent control court seeking its permission to deposit the rental amount with the court.
All these legal processes will involve more than 6 months time, by which you can comfortably shift to any other place of your choice with no much expense.
Once you have shifted to some other place then the landlord will run behind you to collect the arrears of rent through court or in person.
