UTI Pan Card — Pan card correction

For last 10 years I am trying to correct my wrong dob in my pan card. I have applied 3 times since 2011 to uti sl. Since I did not get any result, I recently applied through nsdl for correction of my pan card. But now income tax deptt has put on hold my appln since there are numerous applications. I request utisl to please delete all my previous applns with them so that I can finally get my corrected pan card thru nsdl.
