Why didn't you send me the activation code of Youku vip member's monthly card purchased on the mobile phone?

You can view your transactions in the mobile app. If the transaction is confirmed, there will be a transaction record, which can be obtained by calling 10086. Another possibility is that your mobile phone number has been automatically bound to Youku, and it will be automatically renewed after you pay the money. You can check whether the date is postponed on Youku's VIP member page.
