More than 1500 people have complained Saturday's X Factor final was fixed.
Leon Jackson's dream came true when he was crowned winner of the ITV programme.
But now, loads of doubts are being cast over whether he won fairly. Members of the public say they couldn't get through to vote for Rhydian.
Now Ofcom, the organisation in charge of making sure tv competitions are run fairly are investigating.
Some people say they called more than 50 times. Even Wales' First Minister Rhodri Morgan tried.
He said: "I can confirm at 10.29pm on Saturday I attempted to vote for Rhydian and I couldn't get through.
"I didn't hear him sing, but I thought as a loyal Welsh person I should vote for him, but I couldn't register my vote so my telephone bill will be smaller."
'Fair and square'
Some fans reckon the result was fixed.
But ITV is insisting that the result was "fair and square".
Rhydian was the favourite to win throughout the entire competition, so it came as a big surprise when Leon eventually won.
Leon's first single When You Believe has been officially released today, and is expected to be the Christmas number one.
The song, originally released by Mariah Carey and Whitney Houston, is already at number one in the mid-week charts on the strength of downloads.
