Landlord — Dispute for security deposit not refunded

Address:

E 2203 alpha corp gurgaon one sector 84 gurgaon

I shifted to gurgaon one society in sector 84 gurgaon landlord name is Vinay vaish. Before shifting I sent 34000 to his Citi bank account. 17000 as security and 17000 as advance rent. I always transfer rent to his Citi bank account every month. I left flat on 19 July and handover all keys to flat care taker. Since that day I am chasing them for security amount refund that is left for 12 days. Now they are unnecessarily charging me like 1100 Rs for cleaning and 1000 for chimney service. These things are not mentioned in rent agreement neither they verbally told me. I accepted that and asking them to send rest of the money but from last 10 days they are not responding on calls not even reverting on messages. They are harnessing me from last 48 days.
