TMart N&K Trading uncooperative, customer no service, defective, obfuscation, delay, North Brunswick, , New Jersey

I purchased, among other items, a Cree LED Cycling Triple Headlight with a Lithium Ion Battery Pack.
The Light is great even though it was slightly high priced at about $70.00. The battery pack would only hold a charge for about 15 minutes. It is advertised at 3 to 4 hours. I tried to contact them and finally got through to them by e-mail. They said to send the item back to them. I sent the Battery Pack back to them, and after over 5 months they are now asking me to send the Light Head and the Charger (both of which work perfectly well) back to them. They want me to pay for shipping. I keep being asked to invest more money in a DEFECTIVE product. I am reluctant to send the light back because it works fine with another battery pack that I have and I am worried that I will never see the light or the battery pack again. In my e-mail correspondence with them I have had e-mails signed by a different person each time. Nicole, Gin, Shannie, and a few others. With so many people in their customer service department, you would think they could satisfy at least one unhappy customer. At this point if they are not going to send me a new battery pack, then I want MY battery pack returned to me. It is my property (even if it is defective) and I want it back. 

As others have noted, they do not want to take the simple approach, and it seems that they are just trying to wear you out so you will go away. Well I believe in principle and I do not want to be cheated no matter how minor the issue is. I have contacted the North Brunswick Better Business Bureau, sent numerous e-mails, and will continue to tell the story of their lack of customer service to any one, blog, forum, website, that will listen. I plan to inundate them with e-mail and will try everything in my power to cause them to cooperate. It is now entering a principle state.
