Query: Great Idea - but didn't work !

This is the only cordless clock-radio phone I was able to find anywhere, so I bought it.I followed the instructions which were extremely easy to understand. After the 12-hour charging time was completed,the battery beacon on the LCD screen was reading "low" so I continued charging it for 12 more hours. The condition didn't change. I returned the product and exchanged it for another, thinking it was just a "bad" one. I repeated the set-up instructions again and it was the same as the previous. I returned it again, and got my money back.
