I subscribed to the annual Gold membership today and upgraded to the Platinum membership on the same day. However, I was charged the annual fees for both memberships, with Platinum only an expiration date of one year. Please advise how I can obtain a refund for the Gold membership fee.
您好!我的小孩刚开始学习国际象棋,前几天在我手机上下载了这个App,误选了钻石会员,想先熟悉一段后再决定什么会员,想问一下如何退掉已经订了的会员,在线上一直操作不了,谢谢了!
