Completed treatment and bottom front teeth are still crooked. This is with me wearing my retainer all day…

The dentist I saw for my Invisalign said he could refer me to an ortho…what could an ortho possibly do to fix this short of making me pay for another whole set? I just want to fix the bottom two teeth.. 😓. Pissed that I paid $700 for my retainers and wear them ALL DAY and this is what my teeth look like ..it’s not noticeable from the front but I want these bastards to be straight!

Do u think I need braces for those teeth?
