Here is an extract from Money Box on Radio 4 last Saturday which sadly shows that little in practice is done.
"If you are registered with the TPS, and receive a cold call, you can complain to the TPS who will do a first round of investigations and pass the company's details on to the Information Commissioner's Office (ICO).
But the ICO has not been doing enough to stop rogue companies, according to Mr Mitchison:
"They haven't made any serious enforcement action for quite some time. At the beginning of this year, the ICO were given increased powers.
"They can now enforce a civil monetary penalty of £500,000, but they haven't done anything in the area of the TPS as yet.
"It's very frustrating. We obviously receive a huge number of complaints each month and we receive telephone calls from people that are being deluged by this type of call - particularly in the area of PPI and accident claims."
Ofcom figures show that complaints about cold calls trebled in the first half of this year, with nearly 10,000 complaints lodged in July alone."
