Super Voucher Offer Glitch

I was having a problem with the “Voucher Super Offer” in the FC Mobile store. The pack has an unknown currency and is worth 4,999 of whatever currency it is. I would like to get this pack but I can’t purchase it with any of the normal currency’s, but when I select to purchase the pack it states “insufficient currency () to preform this action”. Obviously it doesn’t state what currency is needed to do this transaction, so I hope this can be fixed so the pack is available for me and anyone else to purchase.
