[Resolved]  Wipro — pf withdrawal query not responded by wipro ltd

I was a former wipro employee who worked from july '2013 till jan' 2015. I travelled abroad later on with my family and continued working in another company. After leaving from wipro, i did not withdraw pf, hoping to get a new job in india after we come back to india from abroad. Now i am back, but due to a personal reason, i want to quit my career. I want my pf withdrawl. I have my uan number and everything, but the balance shows zero. I contacted wipro at [protected]@wipro.com to help me with the withdrawl, but i have not received any response after i contacted several times. I have had similar experience in the past with wipro. I have followed 3 times now with my employee id, but i did not have a single response. There is no number or escalation email id mentioned in the exit letter as well. What should i do? I have no clue. Any help will be highly appreciated.
