Why did the support service stop working? 20 days waiting for an answer to my ticket
Seriously? 20 days without an answer from the support?
It does not matter how serious is your ticket but waiting for that long is not acceptable unless there is something wrong with their support system that (maybe) make them miss your ticket.
Sending a pm to mariha96799 or Chadme can be a better solution for you as both users are still active in this forum.
They might be active but it do look that he's been ignored and try to look that he had posted up into this thread about support ticket response delay but the admin(mariha) didnt really make out any answers or response
towards that issue.
Waiting up for a long time for you to get some response from the support is really not a good thing for the site. 1 or 2 days delay is acceptable but talking for a freaking 20 days?
