I went to purchase the £44.99 which i believe is 9200 gems. It came up with the error...

"Error: you already own this item"

"Store Error: Store purchase failed duplicate transaction"

It only happens with this gem pack.
I am using android mobile and android tablet. Both Samsung. I have tried:

-restarting game.
-restarting phone.
-uninstalling game app.

On both devices.

I already reported this to customer service who told me to post here.
