Why did the bank close my credit card account? I have payed over minimum on my account for over 4 years.?

They did you a favour. GET and STAY out of debt!

The interest rate on a credit card is irrelevant, because you should be paying off the full balance every month.

I think there must be a misunderstanding in Expirian saying it was your income to debt. Maybe you misunderstood that they meant debt to available credit. Credit bureaus have no information at all on your income. Call Experian back to clear up the confusion about using your income and ask for a copy of the credit report on which they made their decision. Or get free credit reports from all three bureaus . I can't remember the exact site name but google free credit reports. Be sure you get the ones that are free and not those where you sign up for them and have to pay.

Banks are trying to reduce exposure to risk be reducing what is called "uncommitted lines" -- that is, the differnence between all the credit limits extended and the actual balances. This is money the banks have to come up with if everyone all of a sudden went on a shopping or balance transfer frenzy.

SO, they are looking for ANY excuse to slash your credit limit.

Yes, this will hurt your credit rating because anytime you use more than 50% of your credit limits, it brings down your credit score.

Just due to general trend n tendency they must hv done that.
