Cognizant Technology Solutions — pf withdrawal/closure

Address: Chennai, Tamil Nadu

My last working day was in 2011-july. I have sent asked many mails, and was constantly following up each week for last one 1 year. They asked me to sent hard copies and then soft copies of the documents and i sent to them 4 times already. Still asking me to wait and they are not submitting the forms to pf office. I dont know what is causing too much delay. Is there anybody who got their pf amount from cts? Whom to escalate the issue? I am sending mails to [protected]@cognizant.com
