Razer Hammerhead True Wireless Problem

So my Razer Hammerhead Case is fully charged, but when I finished using my earbuds and put inside, the earbuds did not turn off automatically and worse, it did not charged. I tried turned them off myself and put in the case, but the earbuds did not charged and when I reopened to check, it did not even turned on automatically. So now, I can't charge my earbuds and if I want to use them, I have to turn them on by tapping. I have been using the product for a few months already but I encountered this problem yesterday! Anyone can help? Much appreciated!
