What can I do ?

I just got out of a game where I lost every objective but the thing Everytime I clear my camps on the side of the objective and I was pinging to my team to help no one ever did

I always checked to see if they were low maybe low on Mana but I tried my best to only ask when I had push and they weren't low on health of Mana and I finished my clear in the of the objective but no one ever responded and I just spent 30 minutes slowly bleeding

what do I do when I have prio but no one wants to help and the one time I did start a drag with prio and pinged for help and check they bars all is well but they just based left me and I was killed do I just have to give everything ?
