OK, some bunch calling themselves Call Value are calling numbers that are in the TPS selling cheap calls. They are calling us a *lot*! They call withheld.
So far I have established that they claim to be Call Value and when pushed will say they are Call Value Ltd, which does not exist. At one point they gave a different name which was in adminstration but I forget.
So, playing along I have established they need you to have a residential line with a reasonable level of calls. Then they can sell a service to save money.
So next time they call we pick someones residential lines and get it signed up. Then we can get bills, but we can cancel under distance selling anyway and many other reasons.
Then finally I can report to the Police and ICO. Criminal offences of calling numbers listed in TPS and Fraud (saying they were Call Value Ltd when they were not for financial gain). And I can send them a bill for my time.
In the mean time, I'll see how good our carriers are at withheld number traces!
