PNB — Sign Proof

Address:

Uttar Pradesh

I have an account in Punjab National Bank, Swaroop Nagar, Kanpur branch.
I need sign proof for home loan. I have spent whole day in bank but bank manager and clerk missguide me.
First they told me that i can not provide you your sign proof.
After 1-2 hour they told me that write an application for sign proof.
I have written an application and gave them then they told me that take a sign proof performa from the bank from which you are taking Home Loan. When I asked them do you have any sign proof performa then they told me that PNB does not have any sign proof performa.
They gave me mental harresment whole day.

I need sign proof on plain paper but they have not provide me.

I would like to know that PNB is working like this.
