This is correct. It's not tagged that stole money from you - tagged is just a merchant that someone purchased gold at with your stolen wallet. You did what you're supposed to do and filed a dispute with your card issuer. Tagged most likely will end up losing the money due to the chargeback, so your anger is being directed at the wrong person.
You should be directing your anger to the individual who stole your Google wallet and made fraudulent charges. Did you turn on 2-factor authentication for your Google account yet? Did you at least change your password?
I am trying to find out the identity of the person who made the fraudulent charges--that's why I contacted Tagged. Tagged should be able to quickly identify which user used my card information to purchase goods from their website. I sent them three separate requests as a follow-up of the three separate transactions made through Google Wallet, but did not receive a response for any of them.
Yes, I do have the 2-factor authentication and yes, I change my password quite frequently (and changed my passwords for all my accounts on various sites as soon as I found out about this).
They should not and likely will not tell you anything about who made the purchase. One alleged illegal act does not make another legal -- they can't violate their privacy policy, privacy protection laws of various countries, and the payment data protection regulations of their merchant account acquirer.
Fraud like this is rarely that transparent anyway -- it's often part of a multi-step process to launder money (buy something with stolen money, sell it for legitimate currency) -- and you'll end up with the IP address of a proxy in Romania that's of no use to you or anyone else. It's also unlikely the person that used your card is the one that stole your card -- the numbers are stolen then sold in bulk on forums for $1-2 a card.
What you are going to find is some poor kid who asked his mom to buy him Tagged gold for his birthday, and she went online to some random buy-tagged-gold-now.com website.
There is no bearded Ukrainian drinking his vodka and showing off how much gold he now has to underaged girls. He is long gone with his ill gotten gains.
