IndiaBulls — Loan amount paid but still sending unnecessary emi request to bank

I had used one freedom card of dhani app amount of 350 something but after this I had paid more than this they charged me subscription fees per month extra which they didn't mentioned before . But they automatically deduct amount from my bank and due to insufficient balance bank charge me 417rs for two times.

I tried to call them but they didn't response after I mailed them still not get response.

I want my extra refund back as soon as possible.
I uploaded all the proof.
