I would like to raise complaint against an employee neha working for legal department. As per her commitment confrmd accnt to be settled at 55k if pay 7k. So i paid 7k next day and till now i am waiting fr her call n msg. She has blocked me. Still i am waiting to. Pay 48000. I have marked mail to nodal officer still did not got any responce. Every time i get different nodal officer everytime i shoot a mail.
Now ms nisha and sumit both from sbi department came home to harass me said if i don't pay it will be forwarded to recovery department who have other means to take out money from you. I am ready to. Pay 48k not more than that
Private banks are not partial with thier customers.. For them everyone is equal excpt for priorities. But govt. Bank i dont have words to say.. Rules changes for rich people and middle class people..
