You will not be able to cancel your pending withdrawal request from the G-Loot client.
You have to submit a support request to payment support if you want to cancel a pending withdrawal request. Make sure to do so as soon as possible since our payment team is working to solve your withdrawal request as soon as they can. If a withdrawal has been handled and sent from our end we will not be able to cancel your withdrawal request and return it in full to your wallet.
Please always make sure to use correct payment details before requesting a withdrawal and do reach out as soon as possible when you suspect any kind of error with your withdrawal request.
