Can my bank / creditor keep me liable for credit card debt from over 10 years after I submit a bankruptcy application?

Ten years ago, I had a bankruptcy filing. At that time I thought my credit card debt was secured. However, my bank/creditor also holds my monthly statement with this debt. They said that they had to do this for their books, but if I ever decided to leave the bank I would owe them the money. They claim that my solicitor did not list this debt on my creditors’ lists. May I get this debt erased under the credit card debt cap status? It’s six years in MA.
