Staff at Vodafone call centres have broken the rules about security checks and left customers vulnerable to fraud. Criminals posing as genuine customers have gained access to some accounts even though they failed to correctly answer security questions. A whistleblower told the BBC it happens because of pressure on call centre staff to meet customer satisfaction targets. Vodafone said it takes security "extremely seriously". In February, David Hart from Lincolnshire discovered Vodafone had given someone else control of his mobile phone number. They had contacted Vodafone via the company's online web-chat service and pretended to be him.
