Ofcom's advice on your next step

Problems with your mobile phone -
Privacy issues - nuisance and sales calls and faxes

If you don’t want to get calls from sales and marketing firms, you can add your details to a list, run by the Telephone Preference Service, which makes it illegal for a company to call you for marketing purposes in the future.

The Telephone Preference Service can be contacted at:

Telephone Preference Service www.tpsonline.org.uk Tel: 0845 0700707

DMA House 70 Margaret Street London W1W 8SS

It takes about 28 days after you’ve registered before the ban on calling you takes effect. If you are still getting calls after 28 days, then you can complain to the Telephone Preference Service, using the contact details above.
