Spent diamonds on hero, didn't receive it

As the title says, today (21.06.2019) I have bought a Chromie with the 50% discount for 350 diamonds. Diamonds are gone, I cannot play Chromie since it showes me that I don’t own her

Hey TheVertiego,

Thanks for the report! Chromie has not been on sale since last year. It should not have been possible to buy her for 350 Gems at this time. Please check your transaction history on the Blizzard Account Management website. It can take some time for newer transactions to appear on the transaction site; your gems may have been or may be in the process of being refunded. If you continue to have issues, please put in a ticket with our Support team.

Thank you,
