Query: Travel Doc 900 Nothing But Trouble!

I purchased a Travel Doc 900 speaker and have had nothing but trouble with the product. When I turn the unit off it stays on and burns thru batteries. I probably have wasted 16 batteries until I discovered the problem. Creative Labs refuses to take it back or give me a credit-I bought an Ipod speaker from another company that works much better. I will never buy another Creative Labs product. By comparison, Logitech (for mouses) treats their customers much better!
