I have been using Ticpods regularly for the last few months. I didn't use them for 10-15 days over the Christmas holiday period and now when I pout them into the Charging Base, the LEDs do not light up. The TicPods also seem to be unresponsive as the LED on them also doesn't light up. I have tried charging them for many hours but nothing seems to work. Any idea how can i get them to charge or rest them?
