"Jeopardy!" champion Alex Jacob says he is still waiting on money he won through the HQ Trivia app – to the tune of $20,000.

The trivia whiz took to Twitter Monday in search of answers.

"Guys, I need your help. I won $20,000 on @hqtrivia on June 10 and still haven’t heard anything about payment. Sadly, I don’t think they’re going to pay," he wrote. "Please RT to tell HQ they should honor their jackpots. If I’m wrong, I’ll happily delete this & give $100 to someone who RT’d!"

In a follow-up tweet, Jacob tagged the app's founder, Rus Yusupov, writing, "@rus can you help?"

Jacob then said he wasn't interested in speaking to news outlets.

"I am receiving a lot of interview requests. I would honestly rather just get paid and not have to do any of them. Please make this right @hqtrivia," he wrote.

Jacob won the game show’s “Tournament of Champions” in 2015.

In a statement to Fox Business and Tech Crunch, HQ Trivia said it can take up to 90 days for winners to receive their prize money.

“We strive to make a game that is fair and fun for all players. As such, we have a rigorous process of reviewing winners for eligibility to receive cash prizes,” the statement read. “Infrequently, we disqualify players for violating HQ's Terms of Service and Contest Rules. It may take some eligible winners up to 90 days to receive cash prizes, however 99% of players have been able to cash out within 48 hours of winning a game and we have paid out a total of $6,252,634.58 USD to players since launch.”
