If some free items didn't get paid out because of technical issues, there is nothing you can do to recover them.
All you can do is to trouble shoot so this won't happen again.
If you don't receive or lose any purchased items, then email Player Support from the game's Settings and Help Center. Free items though do not get refunded or compensated.
