I am experiencing an issue due to a duplicate charge.

I purchased this account, but I have received two invoices.
This appears to be a duplicate charge.
Please investigate this matter as soon as possible and cancel the duplicate invoice.

I am Japanese, and I apologize if my wording sounded too strong.
As I am not a native English speaker, I am sorry if there were any inappropriate expressions.
Thank you for your kind support.
I would appreciate it if you could inform me of the current status or progress.
