Disclaimer: I am just trying to shed some light here on CLOSED tickets, so do not take my words for granted.
Recently (about a month now), I reported a severe bug, and the ticket was recently closed as “Solved” (note that is the only default closing option of a ticket).
Now I was kind of frustrated at first, but I realized, maybe they are unable to solve the issue at the moment and maybe it is not a priority nor does it have negative affect on an account.
So sometimes, you have to figure out the answers to your own predicament. You do not get what you want in life, ALL the time. That is unreal.
All I am saying is, maybe there is a reason for your experience. A customer support staff HAS to answer to the conclusion of EVERY ticket, he will not just click Close and get away with it.
So, give everyone a benefit of the doubt, as I am giving it both to you and the CS.
