The legal side is a minefield yes ! However, when you read what is the minimum system requirements and what are the recommended ones, and your own system is way above those and it still isnt up the promised speed quality etc then there is no real argument to make in defense of the claim. and it dont cost thousands to take anyone to court over an amount under $10,000 in Australia it is called a small claim and goes to small claims court where lawyers are not allowed and you present your facts to the magistrate and he decides after the defendant states why your claim is faulty who is right and makes his judgement and either allows or disallows the claim.
If the other party dont attend then judgement will default to you if they try to switch it into a more formal court you can ask for that action to be denied. Any legal help you need with it can usually be had from community legal services for free unless you want them to do the legal paperwork to submit to the court for you,
The cost of making a claim is about $25 and the cost of having the papers served on the other party of about $60
