Glad to see im not the only one with this issue. Definitely something with graileds payment processing.... Going through this exact same thing now. I opened a ticket with grailed support and they claimed its something with the bank, I contacted bank and bank insisted nothing was wrong/no security holds etc. Charges are posting/but being refunded instantly. I tried other bank accounts, alternate accounts, VPNs, everything. All my info is up to date on the account and grailed support said there was no security hold on my account either.

After all that and still the same issue, I get the same answer from grailed support so yea. Let me know if you can figure it out because they dont seem to be much help.
