Hello sir !!

I registered for cpt but my name was registered wrongly by their mistake in all their records. I had sent many emails and even documents and proof  regarding my name correction to Delhi icai bhawan. They said that they have corrected my name. In cpt result my name was corrected but when I proceeded for intermediate registration through online when I typed my cpt registration no.  my name came wrongly.  What is the procedure to correct my name?  What can I do now sir?  Please help me out to sort this...
