Every one of those is confusing. (1) Third sentence seems redundant. It adds no useful information, unless maybe you're privy to internal workings of the system (and maybe not even then). (1,2,3,4) If "the system" creates tickets, why is the app trying to generate them? 'Generate' and 'create' are too close in meaning, for me. (1,2,3) Why am I charged if the charge+ticket (which should be inexorably linked) did not succeed as a whole? I'd expect the charge automagically reversed (or better: prevented) as a consequence of rolling back the broken transaction. (3) If a 'valid' ticket was created, how is it not associated with my account? That seems like an invalid ticket to me! (4) Seems like the entire transaction (charge+ticket) completed, but mysteriously the app is informing me it doesn't need to or possibly has failed to do…who knows what, be cause 'the system' already has my ticket. The first scenario is the only one for which I agree with the suggested conclusions.
