Rejection of AADHAR update 3 times

I, a resident of Mumbai had got my name changed which I wanted to update in my AADHAR. I have to tried to do this 3 times but my application keeps getting rejected. I have given valid documents for name change. First I gave the publication of name change in Maharashtra Gazette. The second time I sent it by post. And now for the third time I tried to use online portal. I had submitted a certificate of identity by gazetted officer on letterhead as proof. However, yet again it got rejected. I don't know what i'm doing wrong. I'm submitting the documents mentioned on the website but I dont seem to know what the problem is. Please guide.
