UTIITSL — Getting pan card through utiitsl is a pain

Address:	Kolkata, West Bengal, 700001

Hi,
I had applied for PAN Card correction through Online & submitted the listed documents to Kolkata UTIITSL office through SpeedPost which was received just within two days.
After 1-2 days, I visited the UTIITSL site to check the status & found that 1 document is required to prove my Father's full name.
I again sent all the documents along with the requested one to the same office through Courier & it also reached within 1-2 days time. But I am unable to see any status update online.
I even called the office number Tel No:[protected] / 22424774. They asked me to send a mail to PAN.[protected]@UTIITSL.com which I did along with a reminder. But till now absolutely no response nor any update in online status.

Filing this complaint as I don't see any other way of getting this resolved.
