Nsdl E-Governance Infrastructure — pan card application is still under process

Address:

Faridabad, Haryana

My pan card number is bdwpk6535q. After marriage my surname got changed. I applied for changes in pan card in june 2017 i submitted my aadhar card as the evidence document. The acknowledgement number is [protected].
Even after three months, the status of the application is still "under process". I filed my income tax returns this year, but i received a message from income tax department that the itr shall not be processed till the aadhar card and pan card are not linked. The last date of linking of aadhar and pan card is 31st august, 2017. I am not able to link my aadhar and pan card as the surname in both are different (One is before marriage and one is after marriage).

As the last date of linking aadhar and pan is approaching, i am in a delima of what to do and whom to approach for quick resolution of my problem.
Kindly help.
