A former member of Match.com is accusing the dating service of fraud, the New York Post reported.
Sean McGinn, of Brooklyn, sued the Dallas-based company, saying that most matches aren't subscribers -- or even people who have ever subscribed.
He said paying members are therefore "defrauded" out of money, because most matches aren't available, the Post reported.
Members may experience "profound personal anguish" and "suffering" because communications with their matches are never answered, the complaint said.
The lawsuit also said that Match.com tries to lure canceled members back by sending bogus winks, the Post reported.
The class-action suit was filed Tuesday in a federal court in Manhattan. The suit says damages exceed $5 million, according to the Post.
But Match.com said in a statement that the suit is without merit, the Dallas Business Journal reported. The company said it will "defend it vigorously."
The dating service has services in 24 countries and territories and hosts sites in 15 languages, according to its Web site.
