<prompt> Human: Im a freshmen in college and my car broke down during senior year due to engine problems. We bought a working engine with a 30 day warranty from a junksalvage yard. They swore it ran. After me and my father installed the engine to our surprise it didnt work. We called back and they quickly offered to repair the engine no charge in fear of losing a sell.. we agreed and they repaired the engine. Four days of casually driving it around and the engine makes weird noises and breaks down again. They repair it again... and to our surprise it broke down once more! Furious with the customer service and overall satisfaction of the product my dad demands his money back. They deny our refund and say they already lost profit on the engine they sold and dont want to deal with it anymore. We call the BBB better business bureau and file a complaint towards their business. BBB gets back to us and says theres nothing they can do. What do you all recommend we do? Money is tight and I need a vechical to get to school. It doesnt seem fair they said the engine would work. Were customers, we payed for an engine that works. Any help or advice how to follow up and get our money back or anything at all would be greatly appreciated.  <response>: Small claims court. Check it out in your locality.
