The answer to this question is, very simply, no.
Once you confirm the withdrawal via email there is no way for it to be canceled.
To avoid situations like this, always make sure that you are sending your coins to the correct address. We go even further and suggest that you should always do a small test transaction first to see if the coins arrive where they're supposed to before sending out the full amount.
The only way you can cancel a withdrawal is before it's been confirmed via email. There are two ways in which you can do that.
1. If you click on the "Decline Withdrawal Request" button in the email and then confirm the action by clicking on "Cancel Withdrawal Request" again, the transaction will be canceled and the coins will be returned to your wallet right away.
2. Through the app: tap on the "Total balance" button.
Next, tap on the "Pending transaction" that you want to cancel.
Then, click on the "cancel withdrawal" button at the bottom of the page.
After the transaction has been canceled, the funds will be returned to your wallet shortly.
