Credit card company closed my account and still charge interest

I am sending this email to find out a question. Can a credit card company close an account, but still charge intrest.On my credit report it says that the account is closed by creditor.

They sure can. Usually up to 180 days worth, then they go to courts or collection agencies and nasty stuff. Even worse they can add penalties which are stated in your credit card agreement which almost no one reads. These agreements basically say they can charge you whatever they want if this or that happens.
