Similar law in the UK. There is also trading standards who can sometimes help but the small claims court is fairly straight forward. On top of that if you pay with a credit card or any other form of credit specific to that purchase (e.g. a car loan) you also have a claim against the credit provider.
Don't usually need to even go to court anymore as there is a mediation step offered before court. I did this to get a refund for a smartphone that stopped working after a couple of years.
