If you have been called by an unknown company and, upon calling them back, have heard our audio message redirecting you to our support team then it’s possible that someone has chosen one of our numbers to use for the purpose of committing fraud.


A fraudster can set up their telephone to ‘present’ as a number they do not own for outbound calls. This means that a fraudster could call you from a number that is not in ‘service’, get information from you and you would not be able to get back through to them, subsequently, your return call would be redirected to us. If you have given out information on the phone and now believe you have been a victim of fraud we advise you to contact your local police service (on 101) and do your utmost to change the data you provided (e.g. contact your bank).
