Yep, I recently made a mistake of buying a new Lenovo laptop directly from Lenovo instead of Amazon, and it was a huge mistake - the machine arrived with a broken screen and I waited over 2 weeks for the replacement, their support was generally useless and every time I rang them got a different answer to what was actually happening(they said the replacement is ready, only to say it's not and I'll get a refund 2 days later, to then turn around and say a replacement has actually been shipped, absolute nonsense). Had it been purchased through Amazon I can guarantee I would have just returned the laptop the same day with a prepaid label, had the money back in my account the next day, re-ordered and had a replacement the following day. Well, lesson learnt I guess.
At least yours arrived. I also made the mistake of buying a new Lenovo laptop directly from Lenovo some years ago, they canceled the order but didn't give the money back. Their support was completely useless, every time I called they said I had to send an email, and my emails went completely unanswered. When I tried contacting them through the consumer protection organization (PROCON), they sent a nonsense answer (as if I had received a defective laptop and wanted to send it back). I had to sue them in small claims to get my money back (plus moral damages); their defense in court was that I hadn't paid (with a printout of their internal systems showing the boleto as unpaid), even though the initial petition had a copy of the bank receipt. The lesson I learned was to never buy from Lenovo, since I can't trust I would be able to contact their support when needed.
