Hello @YadwinderMehal ,
Welcome back to the Poly Community.
The unit comes back as sold GECDF-Exclusive Networks Pty Ltd back in 16/06/2017
In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.
As the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
