Faulty product caused damage - consumer rights

hP2J68i

I recently purchased a monitor mount for my desk from a seller on Amazon, this product worked flawlessly for about 2 weeks before suddenly malfunctioning today, dropping down onto my desk and actually damaging one of my monitors which is now unusable. 

I have spoken to a customer service rep from amazon and he stated that I would be given a refund for the product if I return it, but I cannot a refund for the broken monitor (which I understand as it was purchased from a Currys PC World store about 4 years ago). The problem is, I need this monitor for work and believe I should  not have to purchase a new one out of my own pocket when someone else's product has caused the damage, surely the seller of the faulty product should be held accountable for the damaged inflicted on something of mine?

I believe I should be entitled to some sort of compensation from the Amazon seller for my monitor but wanted to find out exactly what I can do in this scenario before I contact them directly.

Any ideas or guidance would be much appreciated!! 

Mnoee
