Cognizant — I am complaining regarding the pf withdrawal

Address: 560016

My emp no is 294821. I applied for my pf and it got rejected due to member contribution differs/member contribution differs and tried following up with lenin, arun devarajan & ravi srinivasan but still now i haven't got any reply from these people and i am trying to reach the mobile no [protected] but there is no people to answer and is this the service do we get from cognizant for an x employee. And i am trying to apply pf from march 2018. I am really fed up of this. So i request you to provide me the right mobile number so that i can sort this problem asap.
