Nestaway Technologies — Refund for my deposit and nestaway charges

I moved into the property on 1st dec the rent and maintenance have been increased within my 3months of stay. The increase in rent was notified on 20th feb and asked us to reply and move out with 1st mar. Now as I have scheduled my move out the team mentioned that 45 days notice period will be charged if I don't serve the notice period am not moving out on my own wish am moving out because of the bad service provided by nestaway and when in the mail nestaway gave us only 10 days to move out then why should I serve notice period or pay charges. Is the rules only imply to us no rules for the company exploiting and harassing the tenants
