What is your status, is it pending or Standby ? For international banking it is not unusual for it to take a couple weeks to verify and that is probably what is the hold up. If you use Pay Pal it is a few days.
If there isn’t standby or pending then you should contact the Seller Portal Sign in click on Help then click on Contact Us. If a pop up shows asking if you meant samsung.com ignore or close it. Fill in the form putting N/A for any non relevant by mandatory box and ask for an update on the Status.
When I applied the were very strict that the bank information be exactly the same as the seller ID’s name and they don’t tell you what the issue is unless you ask.
When I applied years ago my ID had 3 names and the application only had room for two names First and Last I had to change the first name from First to “First Middle”
