just had a strange glitch happen and its worrying me

so, I was JUST in a game of 5v5 flex, and all the sudden, my client disconnected, and i do what i usually do if it doesnt resolve itself. I turn off the client then log back in, and usually im able to reconnect, this time however I was not able to, and the match isnt in my match history, and it just let me queue up for another match. I know this ISNT how this is supposed to work, has anyone else had this issue?

Update: something odd happened in my game i just finished, the one that the last incident let me queue up for, anyway, this time a user from the last game was on the enemy team yet again, at any rate, massive ping spikes, right at the end, when my team was about to win.

I suspect, that the user MAY be hacking. though I cannot confirm it. the enemy team proceeded to gloat, that we have no control.

im concerned about this greatly.

update 2-still no word on this, has this been happening recently, is it a new feature in ranked that if you disconn you cant reconn or does this sound like someone hacking or exploting?
