Landlord Harassment — property/unjust power usage charges and refusal to return security deposit

Address:

8a/98 Ground Floor WEA, Karol Bagh, New Delhi, Delhi, 110005

I am residing in karol bagh in 1 room attached bathroom. The landlord is refusing to renew the rent agreement and wishes to switch to tenancy at will. Apart from that he is charging 10-20/unit for electricity use. Our bills are categorised under residential slab and not commercial. I requested him multiple times for renewal of rent agreement or return of my security deposit. Even after installing submeters for electricity he is forces us to pay 10-20 rs /unit.
