my trove

my trove nickname: pitchtao

On December 25, 2019 at 9:00 pm Korean time
I bought 3250 credits for $ 19.99 at TROVE Marketplace.
My steam wallet paid $ 19.99 and came with two training cards. But 3250 credits did not come. I contacted you about this issue 25 days and it didn't work. So ask again.
Please solve the problem. Don't make my 19.99 $ trash.
