AGAIN!!! How can i prevent this from happening.

Seriously it happens way to often 1) A jungler comes to my lane. 2) i ping him back. 3 TIMES. i had no way to follow a gank up/ 3) he goes in anyway and feeds a kill. I cannot take it any more! and i will not! This time it drove me bonkers. This time my jungler did this against Olaf, who snowballed my ass, and ofc i got flamed. i started feeding intentionally just to punish him, but tbh, against snowballing Olaf there is no much difference between intentional and unintentional feeding. I DO NOT WANT THIS SHIT TO HAPPEN EVER AGAIN. how to prevent this?
