I've analyzed the information on your request in detail. As I mentioned earlier, you did send the wrong logs. The record of J337VPP (2019-07-10 20:29:32) is valid, but the serial number is different from the one you sent.
The double charge credits were returned to your account, probably you weren't informed about it at that moment.
Thank you for the request, in the future, if you have any questions about our products, please contact our customer support, we are ready to help you.
