1. Because your card is spent in Taobao and JD.COM, please contact relevant departments in Taobao and JD.COM to check the consumption information of your card. You should be able to find the registration information of that person, such as mobile phone number and ID card information.
Since the swindler has already spent it, he still has to mail it to him to get it. Check the mailing address. This is a clue.
