To close your Save account:

If you still have money in your Save account, you’ll need to transfer all of the remaining balance into your Wallet before it can be closed. Transfers from your Save account(s) to your Wallet can be used immediately to place an order to buy investments or withdraw to your bank account, but withdrawals from Sharesies usually take up to 1 business day (or longer if we need more info from you) to land in your bank account.

Any remaining interest you earn will be paid into your Wallet at the end of the month. You can also choose to withdraw money from your Wallet into your bank account.
