I'm using Linux. Never got any support not puzzled by this. Most if the time I am on my own, ansd most of the time I get more info from google than from any IT support...
omg yes, the amount of times the company says they "support Major Linux distributions" and then when you email or message support they respond with windows troubleshooting steps REPEATEDLY and act clueless when you try to clarify, is unreal. I've even been told "sorry I don't know how to troubleshoot non-windows systems so I am going to have to put you in for a callback"
