5paisa MAB working

#1
Few years back I had an account with 5paisa.
I paid them 7999 for Trader Terminal , this was suppose to be adjusted towards my brokerage.
My account statement with them says that the amount of 7999 was debited but it never shows any credit back. Thus according to me 7999 was never credited back to my account. Atleats account dont show this.
5paisa says that though they havent credited this amount to ledger account but they have adjusted this towards brokerage directly while preparing the bill. They say that the adjustments are done under the MAB colum in backoffice.

Freinds, if you had or are currently trading with 5paisa please tell me how is the MAB calculated. How is the advance brokerage adjusted. How is the advance payment of 7999 adjusted towards the brokerage .
