Well, how are you deleting the User records?
Other than that, is there anything in the log files about foreign key reference violations?
Can’t surmise much more without more source code.

I believe the reason it is not calling before_destroy on the dependent records is because it does a mass delete of all the subscriptions which is much much much faster than loading each of the records in order to call it's before_destroy hook.
I tihnk the workaround you came up with is the best compromise of architecture and performance.
