Power A Wii U Pro Controller Not Working after Dropped By My Brother

My Power A Pro Controller mini hasn't been working since my brother dropped it. He was playing some Mario Kart 8 and then raged and dropped the controller. I had tried charging the Power A, but there was no light at all saying it was charging. Then i tried with a different charging wire but it still didn't work. i have tried pressing the sync button on the back but it still doesnt work. i tried connecting it to bluetooth on my computer but the computer couldnt read it. i hadnt tried the reset button yet since i dont have a pin. Can someone give me a way on how i can fix this?
