Team DC and no loss prevented

Please riot, your servers haven't been so great lately, and today aorund 2:30PM or so they lagged again. Me and my team were in the lead at the moment 7 kills to 3, all of us freeze cant move, but we can type...we all die within 1 min of that time and score it 7 to 8, the lag stopped and we all started playing again but another minute goes by and we all freeze again. We all die again and score 7 to 13....It gets to the point where we cant type and im not sure about the others but I was able to see the progression of the game 5 mins goes by and they take about 7 of our towers. I finally quit and reconnect but was unable to. I give up and 15 mins later log back in and I look up my match history and it gives me just a loss, not a loss prevented. Sorry for the mad grammar but i really dont care at the moment, could u just please give the people that lost in that time spam loss prevented. you didnt start giving loss prevented till 3:00pm.
