When you purchase United Club Access as part of the packages offered when you buy your ticket, the packages that offer UA Club Access, Premier Access, Extra Miles, etc, are you still subject to get denied club access when one-time passes are not accepted?

I purchased Club Access for an upcoming trip but began to wonder if I should have. We don't fly often and wouldn't have any use of the passes at a later date if we were denied access. Ironically and oddly, earlier this week, UA removed the passes from my wallet and refunded us the money, without any request from me.
