Reply to TP2 update voucher for 2nd hand purchase

After much dismay with NI customer service, I was about to title this thread "Native Instruments encourages pirating and switching to Serato Itch" but thought that's be a less productive headline.

My question is this: Has anyone purchased an s4 from someone and gotten an update voucher from NI, and has anyone had problems with this?

I purchased an S4 from a friend who has cancer, and I cannot reach him to ask him about the update voucher, not do I want to bother him while he is going through hell.

I was told by email support that I needed to take certain steps, which I did, and then was told, several emails later, that I had to call to get the voucher. I called today and was told I am ineligible as a second hand user. The guy on the phone was nice but had his hands tied. He even asked a manager, who said they are not obligated to provide the update voucher.

This is the most ridiculous thing I have seen. I had a hard enough time getting the registration transferred and at the time was assured I would receive the update. I do have it in writing in emails and I am going to fight it.

I am seriously considering dumping traktor after all this and trying out Serato Itch as my next system.

Any feedback from someone who has actually received an update voucher after having bout the s4 second hand would be helpful.
