Icai cancelling my ipcc group 2 result

I have passed IPCC group 2 in Nov. 17 attempt (in three attempts). Now ICAI is saying that my group 2 registration was not done and unfortunately I don't have any proof for that, so they are going to cancel my result till 13 March 2018. ICAI has never informed me about this registration issue earlier when I got failed 2 times. I have only a few days left to do anything. I have gone to every department of ICAI including HO at ITO but nothing is working out. Please tell me what should I do to save my result. I am even ready to repay the registration fees.
