John Cheeks says his numbers matched the D.C. Lottery website. After claiming the website numbers were wrong, lottery authorities refused his award, NBC News says.

“I got a little excited, but I didn’t shout or scream,” Cheeks said. “I politely called a friend. He advised me to take a photo, and I did. I slept.
Cheeks was disappointed when the D.C. Lottery online numbers did not match the January 7th Powerball drawing.
The D.C. Lottery website displayed Cheeks' numbers and the $340 million Powerball prize for three days, according to his lawsuit. He learned lottery contractor Taoti Enterprises posted the erroneous numbers.

Cheeks claims in his complaint that a licensed store rejected his ticket redemption. Cheeks alleges he was denied again at the D.C. Lottery and Gaming award center. A claims employee also asked, he says.
“This ticket is invalid. “Just throw it in the trash,” Cheeks added. I looked at him sternly. ‘In the garbage can?’ Yes, toss it away. No pay. The garbage can is there.
Cheeks consulted a lawyer instead of tossing the ticket.
“They have said that one of their contractors made a mistake,” said Cheeks' attorney, Richard Evans. “I haven’t seen the evidence to support that yet.”
He asked, “What do you do about that?” if a mistake was made. We have a precedent in Iowa, where a contractor confessed a mistake and paid the prizes.
