Need suggestion on my visa refusal of italy

Hi there
@someone with good knowledge plz advise.
My visa for italy was refused I was visiting rome the reson they gave me was .
"Justification of the purpose and condition of stay was not provided"
I was like I'm gonna get it as all the required  things I provided. But later on I realise what a big stupid mistake I made what feel that was the reason of refusal I had no idea that vinice far from Rome and by mistake when she asked me what u will visit there .  I said vinice litrally I have no idea what went wrong with me all my documents I provided them was in a good position I feel like that wrong answer of mine became the reason plz someone advise me what should I do now I want to visit italy no intention to stay there I have my own business here  doing fine
