Well... you probably have to discuss that with Aiko. I truly believe that there are serious problems and what was explained I’m pretty sure you would go into shock. My best suggestion would be in contacting Aiko talking to one of the top executives in your division and have them call me. I believe you’ll need to hear it out. 510-502-1470. Pete D’alonzo
