I recently got a week ban from comp because my dad turned my pc off mid game. It's been over 3 days and it still has 150 hours left, is there a reason for this?

Every game in my plat game I don't know if its just me but literally people are one tapping me from 50 meters away in like the speed of light. Like apparently I really need to have 150ms reaction time and tenz aim to be able to kill the jet...
