E.on online account problem - possible ID theft

Minerva69

I've had a phone call from E.on saying that as I tried to log into my online account recently, they have to inform me that due to a technical problem at their end, other customers may have been able to see my account. This may include my name & address, last bill and last payment details, but should not include bank info :mad: They are apparently investigating.

They encourage you to go paperless and manage your account online. If they can't keep my details safe I will be going elsewhere. If my ID is now stolen due to this problem can I take action against E.on for not protecting my details appropriately?
