I paid for an extended warranty on my Lenovo Yoga PC. I needed to have a screen repair done, and spent several hours online with an agent who told me the entire time that the repair could not be performed on site, even though that's what I paid for. I finally demanded to speak to the supervisor, and suddenly, what do you know! Turns out an on-site repair was possible. I need another repair, and I'm now going through the same B.S. once again. I won't ever purchase a Lenovo again. Not only does the company not stand behind their product, they don't even stand behind the up-charged warranty. Garbage customer service.
