I have also checked this number via another site. Like everyone else there - this recorded message rang my ex-directory! Continues even on hanging up. Reading the other posts its either:
Clydesdale Market Research. OR
Hot House Energy OR

Apparently BT traced / checked the number to identify Powergen.

I feel sick. This is my third number in less than 3 years and I went without connecting my phone line for several months in between each change, but we have no rights?!?!.
