Elias here with Shopify Support. Thank you for reaching out.
I understand that you've mistyped your bank details initially and it's preventing you from making the corrections. I've sent an authentication email to the registered email we have on file, please check your inbox/spam folders and reply to it. After I've authenticated your account, I can forward this to our Payments team and they'll be able to further assist you.
Looking forward to hearing from you!
Thanks for the follow-up!
I've escalated the request to our Payments team already; however, due to a higher volume of support requests, it may take a couple of business days for them to review your account. With that being said, our Payments team will be following up with you directly via email.
If you have any other questions on this topic, don't hesitate to let me know!
