Thanks for letting me know. I only bought one bundle so have no spare key. You have a couple of choices. You can tick not recieved, or you can leave a message on this page allowing me to delete the giveaway.
Most keys from Dig work, but in the few instances a key does not I usually don't get a replacement, instead they refund some points (which works out to a few cents).
I apologise for the key not working.
