I despise Natwest.
First problems with them at University, they gave away free 5 year railcards to all students who opened a student bank. No one I knew got one, you only got it if you went through a laborious complaint process. Once I realised I did not have my card after several months I complained, and they refused to issue me one because I waited too long even though it was their fault for not dispatching it in the first place like they promised.
Second problems was with their disgusting ethics when I fell upon hard times.
Third time was when I went travelling and they lied to me straight up about the fees I would be charged using my card abroad, which caused problems. (They did settle with me afterwards and give me some money back, but it was another laborious mission).
Throughout, general appalling service speckled with useless calls from customer service research departments asking me how long I had to queue for in my recent visit and other pointless questions. Flacid attempts at 'caring for customers'.
I'm at a stage now where I can move from them, and will do soon. I'm always happy to spend time telling people about my experiences with them and my recommendation to completely avoid them if possible.
I know banks are not exactly beacons of ethics and good business in society. My expectations for banks is low because of this yet Natwest consistently have managed to go to new depths.
