HDFC Bank — Instead of closing bank accounts after many request, status of preferred customer removed and debited many charges in all my family members accounts

Address:

Rajkot, Gujarat, 360007

I have my as well as my family members saving bank accounts (preferred customer) with HDFC bank since long. Due to pathetic services of Mr. Bhavesh Nikola, HDFC rep assigned to my family members account, two years back I decided to close all my family members bank accounts, but with request from Branch Manager Mr. Jigarbhai Mankad and repeated assurance from Bhavesh Nikola I continued relationship with the bank. But all promises failed and finally in October 2015 I requested to close all my family members accounts. I requested time and again for closing my accounts but efforts were futile. Being CFO of Rajkot Nagarik Sahakari Bank Ltd. I used my banking contacts with HDFC Bank people and they tried to resolve the matter but nothing happened. I got SMS reply Bhavesh Nikola that he will close all my accounts, this never happened so far.
To my surprise now I am seeing all my family members bank accounts status of Preferred Customer is removed and there are one or another charges started debiting in the bank accounts. I called up Branch Manager Mr. Jigar Mankad for that almost one month back. He said he will check the things and come back to me, he too has not tried to contact so far.
Kindly do the needful first to reverse all charges and close all my family members bank accounts at the earliest and oblige.
