Union Bank Of India — Fooled me

I am facing a teething issue that EVC electronic verification code appears to have been generated but nothing is received. This happens on incometax portal integrated with union bank of india.

I have been requesting union bank to look into the issue but they are not responding. I wrote to cgo but nothing changed.

After more than 2 months they made a farce of logging a complaint and closed it stating I should contact an email id. I was contacting the same email id since the beginning of the issue.
This is where they just fooled me. I am deeply disappointed and shall close all my business with union bank in days to come.
