Britain's Got Talent viewers can get refunds after Ofcom ruled the show's final misled viewers.
There was an online storm earlier this year following the BGT live shows after winner Jules O'Dwyer revealed how a secret third dog was used in her performance.
The revelation that ‘stunt double’ Chase performed one of the routine’s big tricks led to claims that the show misled viewers.
Show bosses, Simon Cowell and ITV all apologised for what was described as a "cock up" as opposed to a conspiracy.
More than 1,100 viewers complained to TV watchdog Ofcom who have now ruled that the show did mislead viewers.
In it's defence, ITV revealed that they had considered changing the name of the act to reflect the other dogs but did not want to ruin the surprise.
Furthermore, ITV explained how Jules was told that health and safety reasons meant she was unable to bring Chase on stage at the end of her performance.
The channel regarded the incident as an "unfortunate editorial mistake" but claimed viewers were not misled.
Ofcom however disagreed and concluded: "We considered that although [ITV] may not have intended to deceive viewers, the presentation of the act 'Jules O'Dwyer & Matisse' not only had the potential to mislead, but was likely to have done so."
They added: "ITV failed to ensure that viewers were not materially misled by the broadcast vote in the final of BGT 2015, in breach of Rule 2.14 of the Code."
Those who voted for Jules to win can now apply for a refund.
