Hello Michael my name is ***** ***** i will help you with this.
How much are you seeking to claim please?
Did the IP say why the fees went above that quoted?
Did not read the document you signed which said it could be £25k?
Ok - if you signed it there may not be much you can do.
I would register an Online complaint with the official body.
You can do this here at: https://www.gov.uk/complain-about-insolvency-practitioner
They can consider your complaints and see what they can do.
But as the Company is in Liquidation it would usually be the Company who would take to Court. So I would go via this service and register a complaint.
If it is upheld the creditors may get some additional funds. But sadly that is all you can do at this stage.
Can I clarify anything for you about this today please?
