I bought a set of xenon lights for my car from a seller based in China through their website and when they were installed the colour of the bulbs didnt match - as in the two sets of bulbs had different colours to each other. Anyway the seller has admitted they are faulty (i've set them pictures to show), but they want me to return the faulty bulb at my expense and refuse to pay return postage. Only then will they will send me a replacement. I know that under UK selling regulations, the seller should pay for the return postage, but i'm unclear what the rules are for foreign sellers.
Also, as I paid through paypal (linked through their website), will I have any protection from them?
