I was that 1st customer service for several years for HP. My job was to get you to the proper tech,or whoever can help you best. No, I could not authorize a replacement, so don't yell at me when I tell you I can't. And I am not a tech, mostly a call router, and I don't know how to fix the BSOD, nor what causes it. When my computer dies or misbehaves, I call my son-in-law.
When you can't understand the tech, just ask to speak to someone else. Yeah, we disliked the Best Shores policy as well.
