Worst banking experience

The worst bank! Terrible! Emails are NEVER answered. Their products have sooo much hidden information. Nothing just simple & clear. Call centre staff very friendly, but cannot give you clear, correct, straight forward information regarding the different accounts & cards. I received contradictory advise regarding the discovery miles. Why can't they just explain their different accounts' pros & cons in a simple straight forward manner on their website, so that it's easy to understand for anyone, at first glance. Will NOT recommend this complicated bank system they've got going to anyone. They make it sound so simple, but be warned, it's not!
