Basically, and to be blunt, you are going about this the wrong way entirely. PPI is an asset of the IVA and belongs to your creditors, not to you. The ongoing case has no relevance as you have not completed, nor will do until PPI is sorted.
The default situation is normal. Creditors can, and do, report the default every month --- after all the loan IS in default, why should they not report it as such.
As well as refusal to hand over PPI the obtaining of the Aqua card could be deemed a breach as you are still in your IVA until such time as it completes (or fails).
The ongoing case was, again, deferred. This time for "further consideration". We do not yet know when it will be heard.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
