Due to the long delay in activation on battle.net, the code was activated on America. After communicating with Blizzard support, they themselves activated the code on Europe. Now, everything is fixed and the keys are activated with a bang!
Everything works, thank you. Payment at first did not go wrong simply by the payment option "VISA", but everything went through the "VISA / MasterCard" webmoney.
We bought cards as a gift, it was still in March. The person activated the cards the other day (the month of October), everything is fine. Thank you Igroshop!
