Hi
How you feel scammed? Did we removed anything you already owned? If you lost any of mentioned vehicles you previously purchase, please send a ticket to support. They will check what happened, because this is not how it should looks.
War Thunder is not a single players, standalone game published and forgotten by developers. War Thunder is live project that change through the years and evolve. Something, that fits it 8 years ago, now can be problematic and not needed anymore. Yet, we did not removed anything what you already owned.
