Hey I am in the same boat as well. My PGD-PMIR got a similar evaluation (two yrs of study at a non-recognized institution). I have used the contact us page to send them the urls to AIU / XLRI official site containing relevant recognition-related documents and hoping for a positive response from them. Do let me know if yours gets amended to a Master's degree.
Will do - please keep me posted as well, I did the same for now.
