Arena req bundle

I payed for arena req bundle I got my first 2 packs and i haven’t played for a couple weeks and my area packs didn’t stack up. Did I lose them or what happened and help will be great

You only collect packs on weeks that you play. So if you didn’t play for the last, say, two weeks you won’t get those packs until later. You’ll still get 14 total packs, just later than someone who bought it at the same time and has played every week.
