Alex Neill, Which? Managing Director of Home Products and Services, said:
“This massive breach will cause real worry to millions of customers and raises serious questions about how Dixons Carphone has been looking after customers’ data – so it is critical that the company moves quickly to ensure those affected get clear information about what has happened and what steps they should take to protect themselves.
“Data breaches are becoming more and more common, but consumers lack the powers they need to ensure companies are held to account. That is why the Government should give independent bodies the power to seek collective redress on behalf of affected customers when a company has failed to meet its data protection obligations.”
“Anyone concerned they could be at risk of fraud should consider changing their online passwords, monitor bank and other online accounts and be wary of emails regarding the breach as scammers may try and take advantage of it.”
