Police have warned of phone scams doing the rounds and ask that people be vigilant about the information they give to strangers.
Scams come in various guises, from pretending there's a problem with your computer, to charlatans who say they are from your bank, or a Government agency.
Don't be fooled.
If you are in doubt take a name and call the agency back. Don't use the number they give you – look it up yourself so you are sure that you are contacting a legitimate place. Chances are they will have never heard of the person who rang you.
What police did not warn about – and they have no reason to – is the use of phones for marketing.
