Icici Direct — Extra Brokerage getting charged

Team,

Myself Ganesh Gholap, NSDL Demat A/c No. IN[protected].

I have been told by Mr Navroj[protected] that to save brokerage charges, you can choose ICIC DIRECT Neo plan, which will cost max Rs. 20 for any deliveries or buying a shares while trading.
For the same Rs.352 too deducted from my account wherein promise was given he will give Rs 2000 as cashback which was for more charges which i had paid earlier for my Buy and sell of shares.
I am not happy that this is not yet happening as I buy ITC shares last week Friday and still brokerage charges been applied 0.55 % of total cost +GST.
I will launch a complaint in SEBI if same is not setteled, as i have whole recording and proof on this.
Also till the time all this is not sorted I will not going to trade anything IN ICICI.
Resolve this ASAP and refund my extra money which are charged for brokerage.
