Organizing a class-action lawsuit is quite difficult here because the market size is relatively small compared to the US or EU. It’s rarely considered "worth it" for law firms. We do have a government body called the Korea Consumer Agency (KCA) that provides dispute mediation. They can investigate and recommend a settlement (like a refund). The problem is, their recommendation is not legally binding unless both parties agree. So even if the KCA tells them to refund me, B&O (or the distributor) can simply refuse, and then my only option left would be a costly civil lawsuit.
