This is where all consumers need strong consumer protection laws on their side.

In New Zealand for example, the person/company that took your money in exchange for the product or service is always the one responsible - they can't fob you off to someone else. Products must be fit for purpose, and for a time that's reasonable for the lifetime of the product (not just the warranty). They are required to repair, replace or refund a faulty product within a reasonable amount of time. Taking a company to (small claims) court is reasonably cheap - no lawyers required.
