The most recent is a month or two ago when I upgraded my motherboard and cpu and my retail Windows 10 deactivated and I was unable to activate it myself, so I had to contact support. "Support" was rude and insisted on invading my privacy by remotely accessing my system to do "something". It took several days of exchange and they treated me like a potential scammer and I even had to send scan of receipt to prove that I indeed bought a motherboard. Utter scum.
