@antifraud, good work, but stay tuned as this thief is very likely to show up again. The TS user no longer exists.
It is not a shame, it is shameful and with regrets this serious problem will not be solved. Once again CGT shows that it does not do enough, even when it is aware of the infractions. Due to his negligence, dozens of buyers have been scammed and in addition to the blow to his battered reputation, CGT will have to return thousands of dollars to those buyers, as it said it does in this thread:

Although that will not compensate for other damages, such as delays in your projects and therefore more economic losses, or possible legal problems.
Informing the true owner is a good idea, but in the case of models taken from games, sometimes it is not possible, because these companies are very volatile and disappear quickly. Many of the thieves know this circumstance and take advantage of it.
