Where to report ballot irregularities in the recent primary?

I raised a fuss at my polling place because I suspected the ballot I was given did not match my residence address. I have since confirmed that the ballot I was given was incorrect, giving me the wrong races for Illinois State Senate and State House Rep. At the time, the election workers insisted that was the only ballot they had and it was correct for my voting precinct, and I did cast that ballot yesterday. But I'd like to get this addressed before the general election in November.
