I purchased the Premier Download At BJ's self checkout and recieved no activation code. Now what?

I purchased the Premier Download At BJ's self checkout in January 2025 and just discovered I received no activation code within the package.  Then I read the tiny Important box at the top right corner of the package to "Exchange with cashier for product."  I don't checkout using cashiers because I've caught them overcharging me for purchases in the past.  What are my options other than driving back to the store?
