can creditor be asking for any repayments after bankrupcy ended.

Your average unsecured creditor is cleared when you are sucessfully discharged from bankruptcy.

The only creditors that could be asking for repayment will be found at the following link: debts that are not released by bankruptcy. But before you assume that you have debts that do survive, you should talk it over with your trustee to confirm whether or not this creditor qualifies as one that is not released as certain creditors on that list have to take a specific action to preserve their collection rights.
