Query: Good Changer While It Lasted

We ordered this changer last December and it arrived in perfect condition - so far, so good. It worked great for eight months.But then it totally froze up in mid play with five CDs locked inside. Since we live in Hawaii and would have to ship the unit to Honolulu for service, we were concerned about the condition of the trapped CDs (and their eventual return). Trying to contact JVC for "customer service" is a total joke. They have an 800 number with the usual menus but it is impossible to talk to a real person. The only option was to e-mail them which they said they would answer in five days. Customer service? Well, ten days later we get a standard form e-mail telling us to ship the unit to Honolulu (which we already knew) with no mention of the concerns expressed in our e-mail about the trapped CDs.Our search of the internet turned up enough horror stories of JVC "service" that we've decided to heed the first rule of those who find themselves in a hole: stop digging.
