Having seen other reviews with the same story, it seems that something is not quite right with the current Sim only Vodafone deals with cash back offers. People with excellent credit history are being turned down (myself and my wife included) after allegedly failing Vodafone’s credit check. When you speak to Vodafone they tell you that they have not rejected your application at all. They do then try and sell you the same deal WITHOUT the cash back offer!!Very frustrating experience that at first makes you feel worried about your credit history. Then embarrassed about failing a credit check. Then angry about what has happened.
