HDFC Bank — complaint regarding hdfc employee - nishant rastogi (ambala sadar branch) for misbehaviour & using foul language

Address:

Ambala cantt haryana

SIR,
I m registered HDFC bank account holder having account in HDFC bank, Ambala cantt( sadar branch) registered mobile- [protected], PATHIK BHASIN
Mr Nishant Rastogi, # [protected] employee from Credit Card sales, Visited my office a month ago to issue/ execute Credit Card formalities.
There he made several false commitments while signing the documents and issued me a credit Card.
After a span of time 3-4 weeks i messaged him to update me regarding CC not delivered, he gave No response to my whats app messages.
i messaged him again for the same.
what attitude he shows me that you have problem in your address and thats my CC is on hold.
is that customer duty to follow up his credit card or is it a duty of sales team to ask me for my address proof is its not proper?
later he is showing me attitude writing that
" you check your mail first"
is that kind of reply your team responds to their customers & or this kind of behaviour your employees shows to customer after sales service.
At first stage he writes Application is on hold.
when i said cancel my application.
HE SAYS ITS ALREADY CANCELLED.

soo lenient behaviour towards customer and profession that HDFC bank ONLY knows.
latter i have to block him on whats app .
To take proper feedback and to know the exact issue i called him,
NOW THE SITUATION GOT WORSE,
reason being he started using foul language on call,
what he states,
that" tu hogga apne ghar ka vakil, hamari dikaat nahi hai credit card issue nahi hua" hawa mien naa udd zayada, jo karna hai karle.
" hamara sales ka target poora ho gaya"
cc chahiye toh dubara apply kardo.

THIS IS THE LANGUAGE YOUR SALES TEAM USE.
hats off to the employees.
For evidence regarding messages and call details, i m attaching below screen shorts for your kind reference.

please take necessary action asap as this behaviour is not acceptable at all.
