Call CNN's voter hotline with your concerns or problems with voting.

(CNN) - With just three days to go before Election Day, calls were streaming into the CNN Voter Hotline.

More than 21,500 people have called in to the hotline as of Saturday.

More than 7,300 of them registered a complaint regarding voting issues. The largest number of complaints continues to be issues surrounding registration. With the deadline approaching for submitting absentee ballots, many callers are asking what to do if they still haven't received their forms.

Concerns about vote counting are the third most logged complaint on the line. Many callers also cited long lines and other difficulties at polling locations for early and absentee voting. Problems with voting machines are the fifth most discussed topic on the Hotline.
