Income Tax Department — not able to get refund pan auepc 4964h

Address:

Pune, Maharashtra, 4110137

I have paid IT return for year 2016-17, 2017-18, 2018-19, But still I am not getting refund amount.
I am employee, provides tax wherever applicable by Govt. consider this request and pay my refund as early as possible.
Also provide enough Aadhar card centers, if Aadhar card is compulsory for IT return and everywhere.
For middle man, his money is required, so request you don't put hands in his pocket to take money earned by him.

It is very unfortunate, Income tax help desk peoples not able to tell why refund is not provided, they are like statue or robot.
