Margin intraday trading problem

I have created new account on Zerodha and for testing purpose bought SBIN in MIS – intraday. I saw that for SBIM the margin is 14 times. I bought only 1 stock qty so I should have got 14 stock qty but as I checked the position it says only 1 qty was bought. Also I sold the stock and Rs 0.7 profit, so I should have earned Rs 0.7 * 14 = Rs 9.8 but that did not happen. Am I missing something?

if you buy 1 you will get 1
to get margin advantage first you have to calculate it from here

suppose if you have 1000 cash and want to buy SBI shares LTP=280
1)without margin:(1000/280) =3.57=3 shares
2) with 14x margin: ((1000*14)/280)=50 shares
hence you have to put buy order for 50 shares not 1 share to get margin facility.
