I mean which month exactly? What is the amount?
I got this message from Zerodha.
This is to inform you that your account is due for Rs. 75 + GST towards quarterly demat account maintenance charge (AMC) and will be charged today. Kindly check your funds statement to ensure that you have sufficient balance. Any debit balance in your account may attract interest charges.
The AMC charge will be visible on the monthly invoice. You can download this invoice from the Reports section on Console.
I only have Rs 2 on my Zerodha account and it will take 3 to 6 days for me to add funds.
