There is no answer we can give you.  The software does not work the 
way you have described.

The only two possible answers I can think of are:

1.  The user was intentionally lying to you.

2.  The user did not fully understand the question and the situation, 
and therefore gave you an inaccurate response.

Therefore, if you want to be able to give a complete and correct 
technical response, you must gather more information from the user, 
including incontrovertible proof of exactly what they sent to your 
server so that you can duplicate the described behaviour.

Until you can duplicate the described behaviour based on the 
information you have from the user, it will be impossible for you to 
give a complete and correct technical answer.

Just ask for more information.  You don't need to imply anything, 
just tell them that you're trying to test all the possible paths 
through the code, to understand how the system could have responded 
in the way it did.

If they are unwilling or unable to help, then you should tell your 
management that you do not believe it is possible for the code to 
behave in the manner described but that you do not have enough 
information to prove that, and then it's up to them to make a 

Making real-life decisions with incomplete information is something 
that human beings do every moment of their waking life, it shouldn't 
be too hard for them to do it again in this case.
