Sony India — sell chinese product instead of sony

Dear sir,
I am a regular customer of your esteemed company. Few months before i have purchased a sony home theater model no. Hbd-dz350 & serial no-6206946, but in the back of dvd and sound box is written as made in china. My question is that, is it you are not cheating the customer for selling chinease product in the name of sony. And if not please clarify how i can believe that the product which i have purchased is made by sony.in this connection i am attaching herewith some photo of the said product. Your early response will be highly appreciated.
