Personally i think it was successful attempt to get the model without paying a penny. In other words - theft. I wouldn't blame designer for giving the final file to the client, because the project was prepaid and designer should feel safe and confident that he will be paid wor his effort. I always send intermediate and final files to the clients when project is prepaid, otherwise it would be very hard to work. In my opinion, the most to blame for the outcome of this situation is to cgtrader - they SHOULD NOT issue refund without hearing from both sides. This is very ill practise and it should STOP! @uber-illusionist i really hope that you won't leave it like this and will demand explanation and compensation from cgtrader. Please do this for your own and for all your fellow designers good.
