Getting support

Is there a way customers can create, update and close support tickets or must all such things be done via chat only?

I went thru 3 people today before finding someone at SAGE who could actually open a case for F/A 2018

The CATEGORY dropdown on this page lacks a "SUPPORT" option so I chose INSTALLATION 

No matter which SUBCATEGORY I pick on this page all are apparently invalid

"Paying customers should not have this much trouble getting support.
Your the 3rd person who still cant tell me simply how to open a support ticket.
Please just send me the link to the place where I can open a support case."
