The Support claims that my issue is resolved, but it is not
Lately, we've had several people reporting that the Support responded to them that the issue they had was resolved, when in fact it was not. I asked our CM about that, and I learnt a bit that you all might find useful.
The Support handles lots of issues that we get with the game and with our accounts. However, they cannot handle everything, in which case they ask the devs for help. In that extra communication, errors can happen, and the Support gets (and passes to you) the info that the problem was resolved. There may be various reason why this happens, but the important thing is that it sometimes does happen.
So, if your issue was not really resolved, despite what the Support person said, please respond to their e-mail (do not open a new ticket, but click "Respond on website" button in the email instead), telling them that it was not resolved.
My personal suggestion would be to do so politely and with some further details on why you think so (this is highly specific to your issue, of course). I am not saying this to be condescending, but because I know how frustrating it gets and because being polite and detailed will get you much better results than the response most of us would want to send when getting a false "it was resolved" response.
I hope that this helps you all resolve the problems that you still have!
