Armor subscription fee autorenewed, but the service has been shut off

After the first year of an Armor subscription, it auto-renewed and the fee was charged to my card.  A few days later, Windows began telling me my virus protection was out of date.  When I bring up Bitdefender, it says my subscription has expired, and there's no access to any features.

So far, Netgear support has moved me around twice, and me to reset the router.  This only resulted in the security section of the Nighthawk app being removed. 

Next they suggest resetting to factory settings.  I don't think they know how painful that is, how risky that sounds, and how unlikely that is to resolve the problem.  Since I'm working from home, I cannot afford to be down for a prolonged period.  If I have to start over, I'm wondering if I should do that with a router from a different company?
