xbox不锁区不锁语言，而且风控宽松，是难得的玩家福利，阿根廷区付款方式很难搞，但土区的付款方式还是很容易的。使用xbox土区可以买低价游戏、充值XGP，且资金来源可控不必担心代充黑卡封号。注册oldu一般是采用safeusm申请免费的网络电话号码，之后注册oldu。充值有代充和你自己通过数字货币交易平台的方式。中间可能涉及到因为墙的原因不能访问的情况，需要自行解决。我着重讲从xbox退款这一个情况。
oldu作为虚拟卡，退款与支付宝微信、国内银行卡等都不同。在产生退款时，微软会先将资金退回给oldu，此时oldu并不知道这笔款是谁的（你就当它不知道吧，具体原因我忘了），就需要你主动发送邮件，带着你的相关信息告知oldu客服。
你需要准备的资料：
1、交易信息：发生的时间、付给谁、多少钱，可以从Wallet Transactions中查到：

2、你的oldu电话号码，可以从My Account查到。这个就是你注册时填写的电话。
3、写一封邮件给oldu客服，邮件地址是：info@oldubil.com.tr ，后面是我写的可以参考（我一开始没写电话号码，被回复说需要电话号码，然后又回复了一次电话）：
Dear Oldubil Customer Service,
I am writing to inform you about an issue regarding a transaction for which I have requested a refund but have not received it yet. The transaction in question took place on June 5, 2023, at 23:19 and was for "YD-Microsoft*xbox msbill.info 74.99TRY."
Unfortunately, despite initiating the refund process, the refunded amount has not been credited to my account so far. According to my understanding, refunds are typically processed within a certain timeframe, but it has been quite a while now. Therefore, I would appreciate your assistance in resolving this matter and ensuring that the refund is credited promptly.
Kindly verify the status of this refund and reach out to me as soon as possible with an update on its progress. I am eager to have this issue resolved so that I can continue to trust and utilize Oldubil's services.
If you require any additional transaction details or supporting documents from my end, I am ready to provide them promptly. I kindly request a prompt response to my email and greatly appreciate your assistance.
Thank you for your understanding and cooperation.
Best regards,
4、收到回复，然后退款成功。时间自己看图吧。
