Some players after the release of Overwatch started to complain on the error code BLZOWPAY10200162 that arises during purchasing of loot boxes. When you try to make a purchase the next error message arises: Purchases are not currently eligible from this account. Error BLZOWPAY10200162.
According to developers, they apologize for appearence of this problem and already work for fixing it. So, the only one solution in this case is to wait for its implementing soon.
