Nonexistent Customer Support

I get it, it's holidays, but I've spent over $4,000 on this company over 15 years and they reward me with not letting me access my purchased software. I recently purchased a Used Micro Mk3, the serial number was scratched off so I couldn't even register it. So I purchased the Maschine Mk3 software online, and that worked fine. Yay. I then wanted to upgrade to Komplete, so according to this link on their website: (redacted as they won't let me post a link just look up valid upgrade paths to Komplete 15 Standard.) Maschine MK3 Collection as well as Komplete Select are valid upgrade paths. Well, I purchased the upgrade. Native access says I don't have the valid underlying software. Okay, I'll try purchasing Komplete Select since that's included on the upgrade list? Nope, Still doesn't work. Now I've spent as much money as It would have been to just damn near buy Komplete Ultimate, and these guys still haven't even answered a single one of my tickets. I have 3 tickets open by the way, and I'm going to keep blowing up these forums until they answer. It is completely unacceptable for a company of this size to not have support people on hand, and instead force you to go through AI chatbots and forums to get support. I likely won't go back to NI for music gear again after this is resolved.
