Dear Leader,
Please accept our sincere apology for any inconvenience caused by this issue.

There was indeed a monthly card made on your account and the money we charged is $2.99, so if you have been charged at $9.99, we would like to see what's the problem is on the receipt and we also recommend you contact your card company for more information.

We appreciate your cooperation and patience in this matter.

Thank you for playing Heroes Charge.
Best Regards
