My credit card was charged $29.98 so that I could buy some Linden Dollars,but never got any.It shows that something failed to give me the linden Dollars yet i was charged the $29,98 on my credit card.So where are the Linden dollars?

[Money was taken from my credit card to get some Linden Dollars. But I never got ANy Linden Dollars.]

WHere did the money Go,and when will I get the Linden Dollars?

[Awhile back $29.98 was paid by credit card to get some some linden Dollars. I never got ANY Linden]
