As already stated, the bitter truth - ebay and Amazon just don't care (but honestly, the technical knowledge is not to be expected from a 1$/h agent in India).
Maybe some interesting background:
Check the business numbers. You can even look them up in China. They sell whatever cr*p they want, defraud customers, ignore taxes, legal issues - you name it. *But* I have yet to find a business not stating the correct business registration number. I can only assume there are really hefty penalties in China.
Second: It is common practice, to construct the business of "one factory, one hundered sales agents/sales companies/brands". And it's actually quite clever, when acting in foreign markets. If one seller/brand is burnt - no worries, the other 99 are still in the game, so the factory can continue to sell.
