Thank you for your continued business.
We got the order from our customer to pay the money back.
It seemed that the someone deprived him/her from the authority of the Amazon account set, and purchased any products illegally.
The product has already finished being sent, and we as well as he/she were also harmed because it cost very expensive.
Could you mind if telling me how to cope with that?

I cordially appreciate you.
We will be intent on improving service, and look to you for guidance toward it.
