HDFC Bank — hdfc bank ach debit return charges deducted

Hdfc bank has deducted ach debit charges in my account without any prior information from last two years.

I am not aware why this amount was deducted. I was deducted amount of ₹60, 000 from my account as on date. This is happening for 2 time in a line, part of my salary loss every month.

The bank people are not responding, i have tried calling them and i have also mailed them regarding this issue. But still no reply. One month loss amount screen shot enclosed.

It would be helpful if i get my money back asap.
