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?
You can check with your credit card company to find out what happened and why.
Many credit card companies set one overall credit limit, and a separate and lower limit on cash advances and checks written on your credit card account. It is possible that the transaction would have put you above your cash advance limit.
