ITV says it is going to refund viewers who paid to vote in the final of Britain's Got Talent in June.
You might remember Jules O'Dwyer and her dog Matisse who won.
Matisse didn't perform the tightrope stunt instead Jules used another dog called Chase.
More than 1,100 people complained.
Ofcom - who keep an eye on what television channels do - says people were misled.
ITV have said sorry and offered people who voted a refund or to have the cost of their call or text donated to charity.
