Over the past few days I've been called twice by utility providers I've got contracts with (broadband and mobile). When they call I just say I'll call them back without giving details.
Both times it looks like the number is spam (have Googled). I'm now worried that someone now knows about my accounts and is calling to try and get info.
Is there anything I should do to protect myself? I already have a password on my credit report services due to a previous identify fraud a few years back!
