I tried the customer assistance route back when it stopped working several years ago. I was told it was my fault and it needed a new battery. The thing was, I had replaced the battery the month before. It would randomly just stop working, screen completely blank. It was supposed to notify me when it got low and never did. I could take the battery out and put it back in, and it would work again, showing that it had at least a partial charge. Since the customer service people were full of bs and I was tired of my steps not counting, I just stopped using it.
