Champ Select in Rank Prob

I've been trying to play rank today and most of the time I just disconnect while in champ select then when I do I it take me back to my homescreen and I notice I missing 3LP from my profile. Happened to me 4 times today... that 12 LP. Lol it's not much but because of this I occasionally get banned from teambuilder (even when this doesn't happen in tb) and have to wait because of abandoning queues (unintentionally)
