Natwest Platinum Card

took natwest platinum master card 9 months ago. I had to pay £1091 balance before 28th of feb or minimum payment. I paid £800 before the last date. And they charge me the interest for £1091 instead of balance amount as them policy like that. Again they charged me next month even i paid full balance before the date. When I asked, they told me , they have to change 2 months interest on same amount as its them policy. I simply cancelled with natwest and gone for lloyds platinum card. I am waiting how they gonna behave.

I went to the Holborn NatWest branch today to deposit some funds into my account. The cashier then told me that, as a advantage gold customer, I could have £80 in my account today. The advisor told me that I had to take a credit card in order to get the cashback after 12 months. As I want a new CC i agreed to take the platinum, as I need 0% on purchases more than 0% on balance transfer (no debts). The advisor failed to inform me that there would be no cashback with the platinum card but only with the gold card. He processed the application without explaining anything at all. When I asked about the cashback he insisted it was my fault I prefered the platinum card, although he had never specified the differences between the 2 cards. I gave them 1 star as I have to on this site, but they deserve none.
