From what I've read here and seen online they're fake contact Trademe and Phillips and get a stop put on further sales from this trader
Phillips may sell plain packaged items to OEM car manufacturers but I doubt they're allowed to be resold as a retail item
Either the trader is being duped by a supplier or knows full well they're fake and is just trying to make it as difficult as possible for you to get the refund thinking you'll just give up out of share frustration my advice is DON'T give up get a hold of Phillips get a hold of Trademe and the ComCom and make as much noise as you can
