Query: rip off

I ordered this used equipment for my son to practice on, however the speakers did not work, the mic was missing. I contacted the seller and explained the situation, he was very uncooperative and refused the return or refund my money. I paid 150.00 used, the new one was 200. To replace the speakers and the mic was 75.00. I would have been better off buying new one.
