Input: I paid for extra for so-called guaranteed shipping. I got the notification that my computer arrived, but got home only to eventually learn that it hadn’t actually been delivered! I’m beyond disappointed and angry that nobody bothered to contact me if there was a delay. And even angrier that it said it was delivered when it wasn’t. I really hope the seller gets back to me to sort this mess out.

I’d give a different rating if I actually got my computer.
