I assume that many people when scammed contact the Police and probably talk with family, friends and neighbours in order to warn them.
However a legal web site surveyed people on this and the results are a little surprising.
This is a very small scale survey but is interesting.
On a larger scale, people tend to call the Police if there is an immediate situation or their bank or credit card company or similar or all of them. If the scam is finished then they are more likely to report it online to Action Fraud at www.actionfraud.police.uk or by calling 0300 123 2040
Action Fraud do record the reports and can instruct Police to take action in certain cases but otherwise they do little to help.
If you want your money back from a scammer – then a specialist recovery service will generally have better results than officialdom. Even so the chances of getting any money back is slim.
