Employee's Providents Fund Organisation [EPFO] — pf claim rejection

Address:	Hyderabad, Andhra Pradesh, 500029
Website:	www.epfindia.gov.in

I would like to bring to your attention that my pf claim request has been rejected more than 2 times, even though form 15g and pan (Self attested) copies have been sent via courier.
I have been in constant touch with the chennai office via email (Ro. [protected]@epfindia.gov.in) and have sent the scanned copies of the form 15g and pan copy as per their requirement; still my application has been rejected. It has been annoying as, i need the funds due to being unemployed for more than 6 months.
The contact number at the chennai office is always busy, that way we are unable to get clarity on the status of the claims. So, how does an outstation employee get in touch with the concerned office?
I would appreciate, if this issue can be resolved at the earliest.
