This is what I just found on c2it site, looks like they have disables transfer money from CC to c2it acct:

From which accounts can I Transfer Cash?

You may Transfer Cash from your c2it Account. You may not directly Transfer Cash from your linked credit card account, debit card account or bank account. If you'd like to move money between your linked accounts, first Add Cash to your c2it Account from one of your linked bank accounts and then Transfer Cash from your c2it Account into one of the linked accounts.
