Punjab National Bank Housing Finance [Pnbhfl] — Regarding Home loan Closure

I have a home loan with PNB HFL and i requested for BT to other bank for better roi. Now, Initially they told me it will take 21 working days to get letter, its been more than a 1.5 month they have not provided me any letter. Even i have contacted many times customer care support every time they are saying its in process wait for few days, every time i called i am getting same response even they are not sharing any detail that its pending with whom, I visited bank as well no response from them, Then i complaint nodal officer (Via email ) no response from them i sent 5 followup email no response from them as well. I am really frusteted with this kind of behavior from Govt Authorized bank. I am feeling helpless as no one is giving information and looks like they are delaying without any reason.

PNB HFL guys says i have to pay 3% pre-closing charges and minimum time they take to provide foreclosure latter is 15 working days.
They literally create lot of problems and delay the issues. In any other bank you go there is no pre-closure charges and foreclosure letter will be given within a day.

@PNB HFL: Please grow and satisfy the customers to retain them. If i have to go for loan again you are making me not even think about PNB HFL.
