The Hard Rock World Tour support staff can review all transactions using Hard Rock World Tour's payment options (Credit Card, PayPal, Mail-in.) Players who have concerns about any payments made through any of the Hard Rock World Tour payment services should contact us directly with a Help Ticket.
The Help Ticket link is found at the top of this support page.
It is also helpful to refresh Hard Rock World Tour if Gems do not appear to have credited correctly. This will update all your totals to ensure they are correct.
Important: Nobody is ever billed for Gems they don't get, but failed transactions may appear on your statement as pending charges for a few days before they are refunded back to you.
