Oh well, second ticket just got marked as Cancelled (Resolved), this was the only one which triggered at least an automatic email reply.
I'm just speechless how unprofessional they become. Just one ticked survived (the Italian one), but no response at all for this one. No calls, no emails even in form of autoreply. None
This is frustrating... thinking about 'licensing' the old way this stupid OS, cause there will be no way I'll spend more money on it.
edit: any answer from GamerNexus? I think Microsoft support will continue ignoring/cancelling support ticket, unless some real sh*tstorm blows upon their heads...
