Banks called the "Bodak Yellow" hitmaker a "illiterate, untalented rat" and "caricature of a black woman" during an interview with "The Breakfast Club".
She also referred to Cardi B as a "poor man's Nicki Minaj" and accused her of having a ghostwriter for "Bodak Yellow".
Prior to deleting her social media account, Cardi B responded by sharing a video of Banks dancing to the song in a club.
"The difference between you and me is that I've never pretended to be something I am not! I've made it to where I am for being myself and staying true to that," she wrote.
In addition to deleting her Instagram, Cardi B also made her tweets "protected" and not available to the public.
According to Billboard, shortly before deleting her account, the rapper also wrote, "I'm from the hood. I speak how I speak I am how I am. I did not choose to be famous people choose me! People followed me on Instagram and the people gave me a platform to introduce my talent.
"I never asked to be a example or a role model I don't want to change my ways because I'm famous that's why I just mind my business. This is coming from a woman that bleached her skin but want to advocate. GOODBYE. Im not apologising or kill myself because of who I am.
