I was try to renew my warranty just a couple of days ago. I called multiple times, Lenovo CS just keep telling my credit card didn't go through(Of course, I have enough credit). And my bank told me there was NO ATTEMPT to shop on my card at all! They just wasted a good chunk of my time(put me on hold, transfer between departments) and did noting. Lenovo is just killing the Thinkpad from all ends(ergonomics, build quality, CS)
