So. In process of clearing up my partners finances.

Entered DMP 3 years ago and now everything fully paid. Debt free.

Wonga, agreed to payments from DMP, account had missed payments but wasn't defaulted, then defaulted without email or letter with notice to default during DMP, that had no missed payments. Account now paid in full and marked as defaulted but settled.

I can no longer contact wonga administrators to argue this, is there a way I can argue this with CRAs? AFAIK wonga is now dissolved? No problem with loan being there but they agreed to the DMP so how can this be a default.
