However, if you still have some activity in your account they won’t allow you to cancel the account, like me Currently my account is restricted from buying and I still have still ongoing order. I can’t make the second payment to warehouse (eventho using another method of payment like Lazada wallet, not Visa card or Alipay) and I can’t delete Alipay either, do I have no other choice other than make a passport just to verify Alipay..? Does anyone know what else I can do?
