My guy, this is just ridiculous at this point. I'm not defending NK, I've never bought anything from them, and as someone completely new the hobby, this is the first I'm hearing of them. I'm just pointing out the bullshit you're slinging.

If the dialogue was literally "hey customer service, I'm having an issue with my PCB, what do I do" "nothing because you broke it" then yeah, that's poor customer service. Until you provide screenshots showing the exact history, that didn't happen.

It is 100% more likely there was back and forth of you explaining that one socket wasn't registering anything, that everything else was working, and that you only noticed it after installing switches. They probably then asked for a picture of the suspect socket, they looked at it, saw damage to socket from you putting the switch incorrectly, and made the 100% reasonable conclusion you popped the fucking socket.

Give a rest, get off reddit, touch grass, etc.
