I apologize for my impulsiveness and thank the seller and support for their help)
There were no big problems, and I highly recommend it
I had to drive with the activation, pleasantly that the seller has a large instructions that tries to help users, but almost all wpn never earned.Activated through the baby
I had to tinker a bit with activation(originally there was an inscription"The wrong region"), but in the end I managed to activate it on the xbox website(redeem), having previously changed the region of the account in Microsoft.
The key of the worker, although I have long understood everything, but thank the seller for suggesting what and how.
Activated without problems
