You need to follow the internal complaints system within the IP firm before making a complaint to their regulatory body. I suggest that you write formally expressing your concerns to your IP, recounting all of the facts as you remember them, and then ask the IP to respond to you in writing. They should be asked to explain why a Certificate of Non-Compliance is relevant for an IVA they accept was never agreed by yourself.
With regard to the money you paid over, what contractual agreement did you have with the IP firm for such payments, and what was to happen to that money in the event that the IVA was not accepted?
