The Professional Couriers — Undelivered and Mishandling of pan card

I was waiting for my pan card from the past 3 month and checking status regularly in the link https://www.tpcindia.com/Tracking2014.aspx?id=VPL[protected]&type=0&service=0 where we don't have options to connect with them because there phone unreachable or always busy and there is no response over email.
One day, i have seen status is delivered with signature but not sure where the package got delivered or whom signature have taken.
Kindly take the action to resolve this issue because not only me others also finding similar issues.
I have never seen this kind of courier services.
