Where can i report a support who refuse to come lane with Heal/Exhaust ?

if i'm adc i will ofc go for lane with {{summoner:4}} and {{summoner:21}} , and idk why my support don't come with {{summoner:3}} and {{summoner:7}} , they are trolling so hard, they are there just to protect me, i think the best spells to protect a adc is {{summoner:3}} {{summoner:7}} . Plz help me to report all these trolls supports with {{summoner:4}}
