When are borders and such comming out for season 7 ranks?

I finished in Silver 5 the DAY before ranked ended (6th of November) however i haven't received the silver border, i know i wont get the ward reward due to only being ranked in solo/duo and not flex as well however, but. just wondering about when they are sent out or if for some reason i didn't receive mine as i got into the rank so late
