Yeah, that can happen; I'm afraid a lot of the processes at car rental firms are still manual labor.
Always keep the documents around for at least a year after renting a car; those are your evidence, and they can match them up with their internal records. (And they'll be the primary counter-evidence if they messed up said internal records)
