Initially buying the gems doesnt seem like an issue. But the Gems I buy, are they going to be taken away by SuperCell 6 weeks later? I purchased gems from someone here a while ago, transaction went smoothly but after 6 weeks I got a notification from Supercell that the gems were refunded. My Gem balance is now negative. How can you assure me that Supercell wont take away the gems I buy from you from a credit card refund later on?
