Query: deceptive manufacturer

Don't buy from this deceptive manufacturer, their service is the worst I have ever had!I got the same model half year ago, and it is not working anymore! Their products will just last for a little longer than the warranty period.And, the wosre thing is their *customer service*. I called for help and they didn't try to answer you any question or ask you the details, but ask you to pay 19.99 for even answering some simple questions! In addition, they told me this is what their service should be. DON'T BUY from SONY AGAIN!!WORST EXPERIENCE ever!
