Credit cards common issues

I received a notice from my card issuer telling me that they were closing my account and that I cannot use my credit card any more. Can they do that?

I got a credit card promising no interest for a purchase if I pay in full within 12 months. How does this work?

I used all my credit and made a payment. How long does it take before I can use the card again?

When I tried to use my credit card to get cash from an ATM, I could not do so even though I know I have not used all my credit. What can I do?

I paid my bill on time last month and still was charged a late fee. How can that be?

Why did I get a low credit limit on a credit card?

My spouse and I had a joint account. We are no longer living together and the monthly bills have been sent to my spouse’s address. He/she has not paid them and now the card issuer is charging late fees. Am I responsible?

I sent my payment to the card issuer but I: forgot to include the payment stub; sent the payment to the wrong address; sent cash rather than a check; sent a check in foreign currency. What happens?

I have let my card issuer know that I am disputing a charge. My statement shows that the credit available to me has been reduced by the amount of the charge that I am disputing. Can they do that?

I went over my credit limit and I was charged an overlimit fee. What can I do?
