I bought some LED bulbs from xenonhids.com two years ago. The bulbs seemed good at the time, but I later realized that they were a very cheap design and way overpriced. Now, after only two years, one of the bulbs has failed. I contacted their customer service and they replied a few days later, saying that the replacement bulbs are out of stock and they'll send them when they're back in stock. However, when I replied asking for a refund instead, I never got a response. They seem like a really sketchy company and I'm just hoping I can get the issue resolved before they go out of business.
