ONKYO 6 CD Changer Model NO. DX C390

We purchased at HH Gregg less than 6 months ago. I have used it maybe 3 times. I got up this morning to find it turned on and playing. I could not turn it off or eject my Cd's. I called about it to the store and i get to eat $169.00 sale price plus taxes 8%. If Onkyo is reading you need to improve your quality of product and replace your defective merchandise. UN-happy consumer. I own your receiver also and will think very hard before i buy any more of your products. I hope everyone else thinks so too. This product was placed in cabinet where nothing was touching it and was ventilated well.
