My Old Navy credit card limit is $1, 750 which I never reached; I've had it for 3 yrs. Just recently I paid off the existing balance (approx. $800). My last statement was received on Nov. 30 2008, requiring a minimum payment of $10 with a balance of $60.00. A couple of weeks later I went to my local Old Navy store to purchase some things and when I gave the clerk my credit card she announced it was declined. She then called customer service, where she as well as myself were informed that my credit limit had been decreased to $100 and that a letter had been sent to me on Dec. 4th. I was purchasing Dec. 6th. I understand that any and all changes in credit limits should be notified PRIOR to the actual decrease. I did not know of the decrease until I went to the store to purchase. Is that legal? I've been reading and I know that lots of companies are decreasing their lines of credit, but isn't there a law that protects the consumer of going through this type of embarassing encounter? I paid for the items cash, but I found the incident to be very degrading and undeserveful. I have always paid on time and have a very good credit rate. Please advise is there is any legal action for lack of proper notification. Thank you.
