beware of sharekhan

i recently open a/c with sharekhan
local dealer asked me to pay 25000/- upfront and promised brokerage of 3p for intraday in future for sell leg only.
when i trade on first day they chage me 10p for buy leg & 2p sell leg.
when i complain, they changed my brokerage to 3p each leg total 6p in intraday,it more then even what i see i see i charges.
so my advice to any one who want to open a/c with sharekhan is to ask written proof of brokerage plan
by the way anyone would advice me what i should do now , iam from delhi

thanks
