tips on successful support escalation

I’m interested to know whether anyone may have a tip on how to successfully get the Customer Care Team to engage on a case and address a problem. I have been trying to get an Armor subscription transferred over from my retired RBR50 to my RBR750 since 12/7/2022, and the trial subscription that came with the new router has run out.

For what should theoretically just be a DB update, this has been an absurd situation. They managed to transfer my renewal that starts later this year, but after failing to transfer the active subscription, I was advised that the trial subscription had to lapse before they could take action.  

Netgear’s SLAs appear to mean nothing.  As an IT professional, I’m baffled.
