Left Promos During Champ Select

When you leave a ranked game, your promos, does it count as a loss, and does it make you lose Lp? I had an issue to attend to, and i had to leave suddenly. Although anyone could make an excuse like this, I am simply curious to know why this happens. Because it WILL happen again. I believe there should be at least a one time opportunity as a caution to not have the same thing happen again
