As the series of consumer investigations continues, Gloria Hunniford, Angela Rippon and Julia Somerville unravel the rising threat of ID fraud, with one of the most shocking stories the programme has ever featured. One man reveals how fraudsters set out to steal not just his identity, but also his home. And they very nearly got away with it. And the show goes behind the scenes with the police team cracking down on the criminals making fake IDs to order. With tests exposing how details on social media can be pieced together, are we making it all too easy for the criminals to get hold of the information they need to steal our identities?

Julia Somerville, Gloria Hunniford and Angela Rippon hear viewers' extreme reactions to customer service, exposing big questions around some of our most vital businesses along the way. As one woman takes extreme action after her frustration with her patchy mobile phone signal reaches boiling point, how does Britain's mobile coverage compare with services elsewhere - and what is being done to make it better? Another woman reaches the end of her tether after spending a year arguing over the faults in her new build house. With the team constantly receiving similar complaints, are Britain's new homes just not being built properly? Plus, how a simple trip to the shops can prove deeply traumatic for anyone living with dementia and simple ways their experience could be improved are revealed.
