Leave buster fail

i have alot of problems with ping/lagg in my area, just bad providers, not much i can do personally. but that effects me 1 in 20 games or so i get afk'ed by super lagg spike and am unable to return do to the lagg.

but just now i was playing ARAM, i have not left a game in at least my current game history + at least 20 more before that, and just now i was playing ARAM. my mouse died, i immediately ran down stairs, rushed threw all the draws in my kitchen till i found 2 replacement battiers. i ran back upstairs and i had been ideal for to long, it kicked me from match. i reconnect start playing and help push my team to victory..... leave buster pop's up after match and says i am being logged off because i am suspected of leaving my team....... i came back and helped push for the win in less then 5 mins of when i afk'ed.... you would think it would take into account if you start playing again and whether or not your team reports you for negative/afk.... i told my team i was trying to hurry, and they were fine with it as long as i was trying...
