Claim Compensation 4U never uses “pop-ups” to advertise its service and the web site never requests that you divulge sensitive information about your bank account, or details of your credit or debit cards. If you are ever asked to provide this kind of information then you can be certain that this is not part of our service requirements, and may be an attempt by a third party to clone or fraudulently access your personal details. If you are ever in any doubt about information requested, please contact us immediately to report any suspicious behaviour or requests to us.
