Hi @Karen Gill,
Welcome to the Community!
As @andewhite advised we can’t provide the information for a failed check.
We use a sales system that takes the personal information you've supplied and cross-checks against criteria set by our Fraud and Loss Prevention team. This Internal Security Check is used to help protect ourselves and our customers against potential loss or fraud.
Should a customer's details flag up as being not accepted against any of these criteria, the order is cancelled and cannot be continued. The system does not tell us what criteria have been flagged against the security check which means we're unable to provide any detail to you as to the reason for this.
In addition, our Fraud and Loss Prevention team would be unable to advise what criteria is checked and what has been failed against. To do so could enable a potential fraudster to bypass these protection systems on future orders, enabling significant loss to be carried out against us or our customers.
