Father Name wrongly mentioned

Dear,

I applied for a PAN card at Bajaj Capital in chennai, when i received the card it was found that my grandfather's name mentioned instead oy my fathers name, i reapplied through a CS form in vellore, after 3 months people returned back all the forms saying that they were not able to rectify.

I have couriered all the papers with the PAN card to Income tax PAN services unit, mumbai.

Please help me to solve this issue. How do i proceed furthe
