I got this answer from support
"Hello MacMoulinex,
Thank you for contacting Wargaming Support.
Since the new patch is so fresh, it might take some time for these rewards to be delivered. Give it a few days and they will arrive, hopefully in less than a week. If after some time you're still not receiving anything contact with us again and we will take another look at it.
If you have any other questions, don’t hesitate to contact us. Wish you good luck in your battles and have a nice day.
Kind regards, Marina Balsa"
