UTIITSL — pan card was not issued and not responding to the mails and calls

Pan coupan no : u - n[protected]
I have apllied for pan card through uti online website and made the payment and i have sent the appropriate documents through post in september 2017 to chennai branch. But my application was withheld for processing on the basis of in appropriate documents and returned my application. I tried to contact their authorised agents (Near halasur police station, bangalore) but he (That authorised agent) was replying that "we dont encourage, support and resolve online applications". I tried to contact customer care no. Even they are not responding properly. Later i have sent my aadhar, vote card, driving lisence along with my application. Again my application was withheld for processing. I have sent an email, still no reply from the company.
