As we have reported, a Vodafone advert starring Martin Freeman, in which the actor seems to be breaking up with his partner but is really trying to leave the phone firm, has been banned for being misleading.

Kristina Auxtova, a lecturer in marketing at University College Cork, says the problem with the advert is that it suggested consumers could leave their contracts at "any time" when in fact they couldn't.

She adds that Vodafone was in trouble just last month over questionable marketing claims.

Advertisers are "pushing the boundaries" when it comes to marketing campaigns, she says, while consumers are more willing to complain.

"70% of the complaints the Advertising Standards Authority receives are about misleading claims," she tells Wake up to Money.
