Ohhh you think the warranty is your ally….
You merely purchased a support contract…..
I trained to resist calling tech support… was molded by it…
I didn’t get a tier-3 tech until the recognized I wasn’t in Latin American region…..
And by then I was l33t !!!

The manufacturers betray you, because the technology belongs to me !!!
