I never bought Chinese m4a4 Sherman

As you can see in the screenshot, I have never purchased the Chinese m4a4 tank, including its gift pack, and I do not currently have the tank on my account, but the official store does show that I have purchased it, which prevents me from properly redeem my cdk code. As far as I know from online forums in China, there are already many people suffering from the same problem as me. I have submitted the work order to the customer service, but I still hope to remind the staff to solve this problem as soon as possible in the forum, because we don’t want to miss this activity. Thank you very much.
