Why isn't my beats wireless solo 3 not charging?

my beats are on 37% so they're still working ok on bluetooth. however, i tried charging them and they won't charge (no lights, nothing). i tried resetting them about twenty times (pressing on the power button and the mute simultaneously for a 10 seconds up to 2 mins). the lights would flash for a few moments, signaling that they are reset, but it still won't charge. i'm afraid my battery runs out within the next couple of days and i won't be able to charge them. please help! i've only had these for about a month now.
