I have received an e-mail from Simply-Rewards by Nationwide banking,however if wanting to register it asks for bank details.All the heading appears to be genuine Nationwide.
This is a genuine Nationwide Rewards link whistonian. Note it starts https.
Are you or have you participated in their rewards scheme before or do you have a Nationwide account of some sort that you use online. A no to any of the questions should put you on alert. Can you copy and paste the link so that we can check it out?
