I’ve bought the season 6 battle pass but don’t have it unlocked, it didn’t regis

Heya @ASSASSINSKILZ 

Have you already checked if the transaction was successful?
If it was and you haven't received your battle pass after a restart of your system, you best wait for 24 just to make sure it's not just a delay.

If you still haven't received your coins after a day, you best reach out to the support team. An EA Advisor will make sure you will get the coins you've purchased.
You can reach out to the support team by clicking on on the link below:
