WeChat Pay purchase issue - request refund for Apex Legends coins

It has been more than 24 hours and I still haven't received the recharged Apex Coins.

Hey sakakishizuka​,

I've removed the payment details from your post as these are public forums - please don't post any sensitive information here as it's visible to anyone, thanks!

We are unable to assist with any account or order issues here on the forums, so for this you'll need to get in touch with the support team directly. You can create a case here to get started so support can check into this with you. Once you've created a case, you can keep an eye out on your case history page for any additional updates.

Okay, thank you. I've managed to contact customer support, but they said they couldn't find any record of my payment, so they can't process a refund for me. However, I've received a payment confirmation email and the amount was deducted from my account, but I haven't received the in-game currency. I don't know what to do now.
