Kotak Securities — non-compliance of negotiated brokerage & terms. debited penalty on exit

Address: Kolkata, West Bengal, 700068

I regsitered for demat a/c & trading a/c after long negotiation with rm khalid hussain. Subsequently, i received welcom kit containing a letter with the information : user id, email, trading code, nominee (Faulty name in spite of submission the pan card & aadhar card), demat a/c no. Bank a/c & name, dp name, one sealed security docket containing pin.
No documents were submitted in physical copies. No client master list, no dis book, brokerage as per web - not as per negotiation.
In spite of repeated request, they agreed to reduce the brokerage as per negotiation but added a hidden penalty clause. This was not acceptable to me and requested to cancel /close my a/c and refund the money debited from my bank a/c. They debited after deduction of huge amount.
In this context, no trading done, trading a/c not activated by security pin, no bids were placed, no contract note /bills were issued on account of debited a/c.
My prayer:
1) refund the whole amount with interest
2) compensation of rs. 10, 000/ for harassment, mentally agony to a sr. Citizen (Investor) of +73 yrs.
3) stringent action against the rm & escalating officer srihari nambier, who did not abide by the company. S terms & conditions published on company's public domain, where there is no penalty clause of exit.
