I received a letter on Friday stating that my Visa would be cancelled either due to 1. serious delinquencies or 2. inactivity.

Obviously I didn't have any delinquencies whatsoever as all my cards are a $0 balance and my credit score is over 700 with no issues.

But then I checked the inactivity on this card and it has only been 6-7 months since I stopped using it...less than 1 year?  This is my oldest card, plus best APR and limit.

Any ideas?  Maybe this is a sign because BoA is the worst bank next to Citi.
