Beware of Reliance Money

I have done a trade in Options and squared off the position at a rate of Rs. 0.10 for 14000 shares on NIFTY. The total trade value is Rs. 1400 and the brokerage charged for it is Rs. 4200 but it has to be Rs. 35 which is 2.5% of the trade value. And I have been charged Rs. 7500 as limit card charges on the same day since the turnover is 79801400 as specified by the customer care executive of Reliance Money. But the calculation of turnover is not mentioned anywhere on their website and when I said the same to the executive, I was provided a link to the NSE website "http://www.nseindia.com/content/fo/fo_businessgrowth.htm". In the website, it explicitly mentions the turnover as "Notional Turnover". When I reverted back to the cusomter care regarding the same, they gave a call and told me that for "Limit Card Broking", the turnover will be calculated as "Notional Turnover", but for "Percentage Broking" the turnover will be calculated normally which is nothing but the product of quantity and premium. After that, I have given a mail to them stating that "Notional Turnover" is not mentioned anywhere on the Reliance Money website and if they are calculating the turnover normally for "Percentage Broking", then it contradicts with the NSE link but there's no response after that. If you look in my case only, for a trade value of Rs. 1400 the total brokerage is Rs. 11700, which is 8.35 times of the trade value. I would suggest investors to beware of Reliance Money as they are lacking in transparency.
