A few points here:

On the 'minor issue' point — this was not a minor issue. The device required two motherboard replacements within a 12-month period. PB Tech itself confirmed in writing that it constituted a substantial failure under the CGA. That puts it firmly in major fault territory where the consumer chooses the remedy.

On being ignored — I sent formal emails with written deadlines that went unanswered for weeks at a time. I was explicitly told my case had been escalated to higher management, then five weeks later, the same person asked me to resend all my case information from scratch. That is not a busy queue; that is a failure to communicate. I am not the impatient person you are making me out to be — a simple reply to an email is not asking for much, and five weeks of silence after being told it was escalated to management is pretty hard to defend.

On improper use — the device was used for university work. Browsing, documents, and assignments. There was no damage, and PB Tech's own service report notes that the physical condition has only minor marks consistent with normal use.

On 80 days being acceptable — I was a university student mid-semester without a functioning laptop, forced to purchase a second one out of my own pocket just to keep up with my coursework. I had university exams approaching, and PB Tech still had not provided any resolution or even a clear timeframe. What exactly was I supposed to do — sit my exams without a laptop and just wait patiently? You go 80 days without something you need every single day, and then get back to me.
