Sorry if it’s already mentioned and I missed it, but could the OP let us know what kind of support was denied for his DSOX1204G? Was it warranty or something else?
OP said in the first post in the thread that
I recently contacted Keysight support but they have point-blank refused to talk to me because I am not a company. This is their reply:
Dear ...,
Keysight products are designed, manufactured, and tested for professional and industrial use. They are not designed or tested for personal, domestic, or household use. While we thank you for your interest in our products and/or services, we are unable to provide you with technical support without a VAT ID or equivalent proof of business license.
which –– at least to myself –– indicates that it was not the support that was denied, but that they refused to even "read" the support request without proof of business license.
I got that. I was only curious about the requested service.
If you call them and say: “My brand new DSOX1204G is dead as a brick, can you check it under warranty?” is one thing.
If you say: “I accidentally bent a pin in the Ethernet socket then broke it while trying to straighten it. Can’t find a perfect replacement, can you sell me the original part? I know how to replace it myself, I’m a hobbyist” is a different thing.
If you say: “Can you please send me another faceplate overlay with Cyrillics, because my mother in law from Vladivostok is visiting us for Christmas and she might want to use the scope and I don’t want to have any troubles over the holiday season? She was a nuclear physicist before retiring” is even a more different thing.
My point is that in US (at least, not sure elsewhere) many lawyer-redacted agreements are not there to be necessarily enforced point by point, but only to give a legal reason to back out off a deal (or deny a service or take a specific action) at the issuer discretion, when they wish so for reasons they might not what to bother to explain. Like in my state, it’s illegal to drive in the left lane unless you want to pass a vehicle driving in the right lane. Nobody gets pulled over or gets a ticket for that, and everybody is doing it. I know a guy who asked the police officer who pulled him over for speeding if his radar was recently calibrated. He learned his speed had been only estimated by “clocking” (not by radar), so he only got a warning for speeding and on top of that a $100 ticket for driving in the left lane. Happened to friend of mine

(he fought it in court and won, not because he had the law on his side, but because that was his only moving violation in the last three years and the judge wanted to encourage him to keep his good driving behavior; “Not guilty!”).
My personal limited experience with Keysight as a private customer in US was not that bad. I bought a DSO from their eBay store and found an issue. I called the US customer support. They picked up immediately, spent time on the phone, fixed the issue. They also provided a direct phone number to call if the issue reoccurs. I got some free software upgrades, too. It was a couple of years ago. True, I was within the return window and the conversation started with “I’m not sure if I want to return it for a full refund or try to fix the issue”. The issue was intermittent ethernet connection if it matters (fixed by a deep hardware reset, or something like that). I also have a separate work account with them (using my employer issued email), but I don’t think they knew that while providing the support.
I don’t mean to offend the OP in any way.
