Okay - free bit of advice here: Since 11th December 2003 (under the Privacy and Electronic Communications (EC Directive) Regulations 2003 for the geeks out there), it is unlawful to make unsolicited direct marketing calls to individuals who have indicated that they do not want to receive such calls. Before you hang up, tell them in no uncertain terms that you do not want them to contact you again by telephone or otherwise and ask them to remove your personal data from their databases. It is your legal right not to be marketed to in the UK by telephone in this unsolicited manner. Also, as someone above has said, you should also register with this site http://www.mpsonline.org.uk/tps/ (go to the telephone preference option). Traders are meant to check with this list before marketing to you by live phone calls (i.e. it blocks out everyone). If you do want to receive marketing calls from traders, they will still be able to call you but you must give your consent to the communication (hence all the "tick this box" stuff when you give traders your personal details). If traders still contact you by telephone and the communication is not solicited, you should report them to the Information Commissioner www.ico.gov.uk. Good luck.
