Sometimes, Instant Withdrawal transactions (IMPS) get credited after a delay of up to 72 hours. This could be due to the bank not crediting the funds to your account.
If you do not get the credit to your bank account within this period, it should be refunded back to your Dream11 account. You can place a new withdrawal request after this.
Note: If you've verified a bank account that belongs to Telangana, Assam or Odisha, your withdrawal will be rejected. If you are based outside the states mentioned above, kindly place a verification request of a bank account that isn't located in any of them.
