Query: Deceptive advertisement for product

I did not read the reviews for this product, which I think is the one and only time I have never done so. If I had, I would not have been surprised when unopened the package and found it not to be a " Yamaha" brand product as specified, but a generic no-name product. The product does appear like the one in the picture and should work just fine, I just hate deception in advertising especially in regards to online shopping when you rely on the honesty of the seller to provide legitimate descriptions of their products and not use a brand name to suck your sale in. The fast mail service would have impressed me to buy again until I opened the package only to see I had bit on a bait and switch.
