"Result not released due to debt" is an error message that pops up when a centre owes NECO the registration fees of its candidates and as a result, all candidates registered under that centre would not be able to view their results until the debt is cleared. 

What you must do, is to reach out to your centre and persuade them to write to their state government to remind them to pay up the registration fees of its students as promised, so that your results can be released.

Noteworthily, individuals who wish to pay up their own part of the debt will not be allowed to do so, as it is against the operational process.
