Royal Bank of Scotland Classic Credit Card

I had my Royal Bank of Scotland platinum card canceled because I did not use if for 85 days. But the worst problem was that they canceled it before I was notified and I had a very embarrising situation when I tried to use it and was told be a dear friend that my credit had been denied. How embarrising when my only problem was that I did not use the card for 85 days. Don't you think that a platinum customer who had paid his bill and never been in default since I got the card in 2002 would have at least been told in advance not to use the card
