The public vote could not have saved Tom from the dance-off
Lots of people who voted say they feel like they've wasted their time and money.
The BBC says that because people are asked to vote to save their favourite from the dance-off they couldn't count the votes for the semi-final as there was no way Tom could have avoided being in the bottom two.
But they promised every vote would be rolled over to next week's final.
Whoever gets the most marks from the judges, gets three points, whoever's second gets two and for third place you get just one point.
That's the same for the audience vote too.
As Rachel and Lisa both got 75 out of 80 from the judges for their two dances, they both got three points, while Tom came last and got just one.
That means even if he'd won the audience vote, to get three points, he'd have finished on four points.
But Rachel and Lisa would have got either one or two points from the votes, giving them a total of four or five. So whatever happened, Tom would have been in the dance-off.
