Apple Watch Series 8 won't Charge when plugged it.

I have an Apple series 8 has been great until I dropped it a short fall maybe 4 ft but now it won’t charge it was charging now for three hours and it has reduced from 79 to 76 % I checked the trouble shooting guide it’s not on low power mode I don’t see any cracks on the charging part I’ve tried different chargers and restarted it still at 76 %
