Dear Sir,
Delete mandate option is available in Advisor login >> Invest Online NSE >> Mandate list menu. See the actions on the right hand side of the table. However, you'll also have to ask NSE to delete the same from their system separately so that it doesn't get synced again into Investwell the next day. When you delete a Mandate from Investwell it doesn't get deleted from NSE as they haven't allowed the same.
