I have been an O2 customer for 10 years using the same email address (only used for O2!) in the last week I have started to receive spam from several companies e.g. "improve your CV" company and a "claims" company both saying

"Your information has been passed to us by one of our partners because they thought you might be able to benefit from our service"

They also use an incorrect spelling of my name that is only used by O2 broadband emails.
Therefore I have high confidence that O2 broadband has given my email and name out to a third party against my preferences.
Anyone else found this happening?
