Mantri Developers — pre emi not paid by builder as project is in delay.

Address:

Bangalore, Karnataka

I had invested in the mantri serenity bangalore on 20 :80 scheme and booked 2 bkh apartment o303 in april 2013.
The developer had offered to pay the pre emi until the project completion. And the project was expected to complete in 2015. Until now the project is not completed and the pre emi payments are stopped from the developer whereas the bank is deduction the loan emi amount from my account. Several complains i have raised by email to the crm team but have failed to get any response or feedback. As i am an nri i am not able to visit the mantri office and follow up.
Need this to be resolves asap as i cannot efford to pay the emi which the developer is suppose to pay and which is pending (Almost 3lakh) rupees and counting.
