This is an accepted solution.
Thanks so much for reaching out! I'm happy to clarify our best next steps to get this resolved.
We'll definitely want to authenticate you as the account owner to give you a hand updating your method of payment. To do so, I'll just ask that you visit our Help Center, log in to your account, enter a topic into the search field, and choose Get support. From here you'll have the opportunity to choose from all of our currently available contact methods (which may include live chat, callback, and email) where a support advisor can reset the number of available attempts to add a method of payment.
I hope this helps and please let me know if you run into any questions!
