Landlord Harassment — discrepancies in the rent agreement and illegal demand for compensation by the landlord

My son ankesh tuhin, a final semester student of nift bangalore had taken the flat no. 004, 1st floor, nsr brindavan annex situated at reliable residency layout, 2nd phase, 2nd main, 3rd cross, hsr layout, bangalore -102 on rent in june, 2018 for his sister and another nift student. There was urgent need, therefore, he signed the rent agreement in good faith without going into finer details of each clause. However, subsequently it was discovered that agreement had many discrepancies particularly reg. Termination of agreement etc. And it was totally one sided favouring the landlord only. The matter was brought to the knowledge of the landlord and was requested to re-execute the agreement correcting all the discrepancies. However, he agreed, but did not take any action and remained unresponsive.
Observing no action from landlord the it was decided to leave the flat short-closing the agreement and one month prior notice in that regard was given to the landlord on 26/12/2018. But the landlord is now demanding for compensations as per the rent agreement, which are inappropriate and illegal.
In view of above, we request for taking up the matter by your forum for investigation and redressal please,
Thanking you,
