Pro Sites second blog sign-up issue

I’m having an issue with Pro Sites where a user who already has a site, attempted to sign up for a secondary site and use a different credit card. He went through the process of choosing a template, then his Pro SIte level, then he put in the site name and url and then the credit card information. Then the page showed up like a blog post and it appeared like nothing was done.

In the background, what happened was, his previous credit card with already active site was charged and a new site was created but the Pro Sites subscription data didn’t exist. Please advice.
