HDFC Bank — Harassment over CIBIL score

Address:

533001

Sir I took a personal loan from HDFC Kakinada, East Godavari, Andhra pradesh with loan account number 22332228.

I cleared all of my instalments.

Today i got a phone call asking me to pay 300 rupees due.

when i asked for which month you are charging, the bank employ did not answer properly and threatened me to refer to CIBIL. I recorded the phone call
She threatened to Spoil my CIBIL scoring.

I wonder is this the way to behave with the customers.

If any dues are there give in writing the details, I will check with the receipts i have. after all everything is Electronic clearence only.
Such are the cheats of HDFC .
arrogant and Irresponsible behaviour by the staff (the Phone call is received at 5:30pm 17/11/2016)
Please update my CIBIL scoring

PLEASE UPDATE AND MY CIBIL SCORING
