This is my story.
Initialy they told me that there will be no charge except the brokerage i.e. 5p/50p and emc that will be charged only after completion of 1 year.
When one of angel broking person called, I said I dont have 25k right now to start with, he said no problem you can start with 10.5k and there are some charges on that but I personally guarantee that you will be treated as 25k customer and no other charges will be there except the above 2 charges. Then I heard god knows how many different charges, terms and conditions, minimum brokerage, account opening fees and what not.
This is not it, closing the account is much more pain in the a*. For opening they will come to your place but for closing you will have to go to their place.
