I bought a domain yesterday September 15, 2012 when the press summit bottom, the next windows say: “There was a problem making this purchase. Do not reload this page. The Domain was registered but not connected to your wordpress.com site correctly.
Support Stuff was notify and will fix the problem shortly”.
Well I check back an hour later and the domain was still available, but my payment history showed the transaction.
Well today September 15, 2012 the payment history shows 2 more charges for registration.
