Query: False Advertising and Tedious Exchange Process

MLC Distribution shamelessly misrepresents the nature of this product. They attempt to pass it off as a new adapter by having Amazon list it as a new product. In fact, it is a used power adapter that has been refurbished. When the adapter arrived, I could clearly tell it was used due to the excessive scratches and other marks. I decided to keep it, despite the false advertising, since I really needed to use my computer. However, after using it for a few days, the adapter stopped working. MLC surprisingly agreed to replace it when I contacted them via email, but they were only paying lip service, as the exchange turned out to be the most tedious and time-consuming transaction I've been involved in.
