Query: No Service After Sale

My stereo started having disc problems. Sharp referred me an authorized dealer and it took forever to get it back. They had to replace the "pick-up" whatever that is. Then it only lasted about a week and it started having the same problem. I contacted the authorized dealer who has kept the unit forever. I have sent letters to Sharp about the terrible service, but to no avail. I will never buy any product with the brand name "Sharp" on it ever again. Buyer beware, no service after the sale.
