People stealing your lanes

Hello,

So recently I have been running into an issue where my teammate will die maybe 2 times in lane. They will then proceed to rage and steal my lane for themselves.

What can I do in this instance? Is it even a reportable offense?

Because I'm getting sick and tired of it, I ended up flaming the last one and got a 10 game chat restriction because of it and had my honor drop to 1.
