Panind — performance obligation not executed and possession of sensitive documents

Address:

10/2 East lokamanya Street, R S puram, Coimbatore, Tamil Nadu, 641002

After sending a copy of my sensitive documents like passport and adhaar card and photograph, panind stopped responding to my mails and calls. They have charged me rs.499 for pan card correction, which has not been done and also have my sensitive documents. Before i sent the documents i got regular response from them requesting for a copy of pancard, and after sending the same they have altogether stopped responding.
Please help me get my pancard and retrieve the copies of my documents.
