If you’ve only just done this:
💬 Type “wallet” and hit "manage your wallet".
You’ll be able to see your transaction and hit "cancel".
If you did it a while ago*:
You might not get the option to cancel. If that's the case, you'll have to wait for the money to clear into your Wallet, and then withdraw it again.
If it’s an autosave:
You can tell Cleo not to make an autosave when she asks you on Wednesday, If you missed this you might still have the option to cancel after she’s moved the money on Thursday.
💬 Type “wallet” and hit "manage your Wallet".
Scroll down on your Wallet transactions to find the autosave. If the option to "Cancel" is there, tap the button. If not, you’ll have to wait for the money to clear and then withdraw it again.
*The exact times vary depending on your bank. As a rule, if you don’t see the button, it’s too late and you’ll have to wait for it to finish pending.
