Very true. Sometimes a product does just suck and a replacement doesn't make sense. I'm surprised they wouldn't send you a refund if they were that eager to try to solve it, but I guess that might be construed as an admission of a flaw they don't want to acknowledge, which some people would then include in a review revision as something even more damning of their product.
Certainly not everything can be worked out, regardless of the level of service. But I think you did the right thing after the fact by at least seeing what they could do to help, and while in the end it was nothing for you now, perhaps it will help them improve their product in the future.
