No gold with purchase

My son tried to purchase 1000 gold (1200 with bonus), with our permission, and he never received it. He thought the purchase didnt go through so tried again and it was the same thing. Now he is out $50 which was a Christmas gift. Merry Christmas to Joycity from my 8 year old I guess!! Email to Joycity went unanswered. Please provide a way to contact you to rectify the situation!
