Hi BMoshier!
3 months? That’s not right. We sincerely apology about it, however I would like to point out after checking the tickets that it is the typical case of sending reiterated responses to a ticket and moving it to the end of the queue.
Regarding your renewal, at the moment the auto-renewal is designed to renew always the same product and for 1 year. In case that you want to renew for more years, a different product and/or more machines, it has to be done manually each time.
I’ve cancelled the auto renewal for your current subscription (can take few hours to be shown on your account in Nexway), so we can discuss regarding your renewal on your ticket.
I’ve taken ownership of your ticket (JGG-469-17226) so let me know about your needs for the renewal there 
My apologies once more for the time it has taken us to reply to you.
