ResolutionH-Sphere doesn't charges CC when there are some problems with domain registration. Domain registration involves two steps:
1. Lock required amount on the credit card (AUTHORIZE) before domain registration
2.a. If domain registration succeeds, debit the locked amount to the credit card (CAPTURE)
2.b. If domain registration fails, unlock the amount and cancel the initiated transaction (VOID)
Some merchant gateways don't support CAPTURE or VOID transactions, requiring that they be performed manually through a web interface. In case of domain registration, you will receive email notifications requesting to complete or cancel a transaction every time a user registers a domain name.
