Address:

Bangalore, Karnataka, 560058

My HDFC bank complaint num - MUMP[protected]
On[protected] Rs) was deducted from my account without my knowledge and i immediately called HDFC bank customer care and reported issue.
They have assured me that within 7 days your problem will get resolved but unfortunately it did not happen.
I have sent countless email to bank about unauthorized transaction which happened on[protected] but no one seems to be worried about my query and i want my (15000 Rs) back to my account without my knowledge amount has been deducted.
I am really disappointed by the poor service of the bank
