Duplicate key LEGO Bundle Nuuvem

Contact their support and tell them the situation.

Yes contact Nuuvem support. What are you doing here? :D

That's no good. I bought the full bundle yesterday just to give them away. I don't want to give others duplicate keys (in the off-chance any of my 8 keys are dupes...) :/

The support should be somehow able to check if the same key was sold multiple times and fix that and about the vpn there should be no problem unless if already purchased with other regions
anyway they provided you a used key for legit money (even if was less then it should)

their support awfull, still waiting for response :/

Last time I had an issue with a key from them they gave me a new one. Though that was few years ago :P
