Been doing a bit of research,
Beyond the first 30 days of ownership you're entitled to a full or partial refund instead of a repair or replacement if any of the following are true:
At least three of these apply.
- an attempt at repair or replacement has failed*
- the cost of the repair or replacement is disproportionate to the value of the goods or digital content
- a repair or replacement is impossible
- a repair or replacement will cause you significant inconvenience*
- the repair or replacement will take an unreasonably long amount of time.*
If a repair or replacement is not possible, or the attempt at repair fails, or the first replacement also turns out to be defective, you can reject the goods for a full refund.
If you don't want a refund and still want your product repaired or replaced, you have the right to request that the retailer makes further attempts at a repair or replacement.
If you discover the fault within the first six months of having the product, it is presumed to have been there since the time you took ownership of it - unless the retailer can prove otherwise.
The retailer can't make any deductions from your refund in the first six months following an unsuccessful attempt at repair or replacement.
