About CDSL
Two CDSL lines matter to an investor. Central Depository Services (India) Limited (CDSL) takes complaints about demat services on toll-free 1800-21-09911, and general investor queries on 080-69144800 or [email protected].
Both work Monday to Friday during office hours. Your own broker or bank, as the depository participant, is still the first place to ask about your demat account.

Your broker first. As your depository participant, it handles account changes, TPIN issues on its app and failed sales, and it can see the transaction from its side. Call CDSL on 080-69144800 when the broker cannot fix a depository-side problem, and use 1800-21-09911 if you want to lodge a complaint about the DP itself.
