I checked your account and it looks like you have not added a billing method yet. To add a billing method, please go to Settings> Billing Method. You can check this help article for more information about the accepted billing methods that you can use. Thank you!
I submitted an online support ticket as well and wasn't sure which was the best method to contact support so I used the Community Bot and wound up here. I added a Paypal account and also want to submit verification.
