Continental Finance Company, LLC Credit Card Complaint

Continental Finance Company, LLC Credit card department,

Delinquent account Delaware

My account has been delinquent for a couple of months. As I was trying to see what to do to settle the account, I realized that the minimum payment is $310.00 while the amount due is only $690.00. There is no explanation as to why the minimum should be almost half the amount due. I want to be able to settle the account but need them to give me a reasonable minimum payment and explain how they calculate their minimum when payments are missed.
