can someone help me??

I have a Razer Kraken BT Kitty Headset.  And about 2 days ago I have been unable to hear others over the phone. I can hear audio just fine, it's only when it comes to calls that I cant hear the other persons voice when its connected to my phone. I can hear them when I connect to my other devices. But for some reason when its connected to my phone specifically i cannot hear them. The headset was working just fine 3 days ago. But then out of nowhere they stopped letting me hear others in call. I have no clue whats going on and I'm scared. I've tried everything I can think of can someone please help me? 😥
