I want to return gold.

Accidentally bought for 2000 gold - 1 ticket. Is it possible to return 2000 gold for 1 ticket?

By ticket I'm assuming you mean Coin.
The answer is no, Trade is made between players and isn't refundable.

Lottery ticket (on the Varman website), I want to return my 2000 golds back for it, is that possible?

Oh sorry for the misunderstanding, didn't even think about the Lottery as I can't recall anyone ever asking for a refund on that.
But the answer is still a no, the only thing we offer refunding support is Coins.

Very sad, thanks for the quick reply.
