Bronze IV player looking for flex premade or a duo queue to climb

{quoted}

i'm currently in b3 and i play jinx and sona mainly

That might be part of the problem, jinx is VERY bad right now, it might not seem like it at lower elo's but when you look at damage and usefulness jinx is at the bottom of the adcs

I reccomend you try learning some new adcs like twitch kogmaw caitlyn or maybe jhin or xayah
