Hi ruoyo, we got your ticket and responded to it on the 16th. We looked into it, and it seems that Steam had an error that caused the purchase to partially fail.
Our team investigated this internally and as of about 5 hours ago, the purchase status was fixed. If you are still seeing issues, please send a response to our support team through email.
You should receive a response to your ticket soon – our support team is under heavy load right now so I wanted to get you a response a little sooner.
