Why did my Funds got transferred to my Bank Account even though I didn't place a withdrawal request?

If you haven't traded in 30 days, the money in your Trading Account will be transferred to your linked Bank Account. The Funds are also settled in a Quarterly settlement process (90 days) and you will get the message that the withdrawal request was processed even if you hadn't placed a withdrawal request.

This is as per the SEBI Circular/Guidelines.
