HDFC Bank — credit card payment related

Hello respected sir/ madam,

This is regarding the credit card payment which is due from my side.
My total outstanding amount to hdfc is around rs 54000/- or so. I am holding hdfc platinum card since more than 3 years and since before that i was having the card which they upgraded to platinum. I am very old customer of hdfc.
Recently i lost my job since month of june 2017, and since than i am some how managing to deposit / pay minimum amount due to credit card of hdfc, however this month (August 2017) i am feeling the heat as i am not in position to gather the amount to run my house expenses and also some of the loan emi. As i was expecting some support from my near friend who assured to deposit some cash flow to run my show atleast this month.
Today at 4:07 pm - on 16th august 2017 i received a call from so called hdfc credit card department - & the number reflected on my cell phone was[protected], the executive name was pankaj suryavanshi - and he started the conversation saying my min bill outstanding towards my hdfc credit card is due immediately - i tried to explain that as my savings account is nil balance - i can only able to make the payment by next week as i am expecting some funds - while doing so - he told me to deposit atleast min of rs. 2000/- if not rs 5, 000- immediately - upon which i told him that as i do not have balance in account i am not in position to deposit even that cash. Later pankaj suryavanshi reacted & he used the language in between and i could make out that it was the indirect threat - pankaj suryvanshi clearly used the words - "now you start thinking about your total outstanding amount".
On using this words i lost my tamper & ask him to check my previous records of more than 3 years - i never delay payments to anyone and even i ensure i should be able to pay minimum dues of credit cards - but as this time my condition is really bad the funds are not there in account - still i told him that i will try to arrange some funds soon as possible.
But the arguments got heated up & he was almost rude in talking, as if he does not have sense to talk. I do agree that it is my full responsibility to return the cash value i transacted. Further he informed me that this will reflect and reduce the limit on the credit card - upon which i clearly told him you may please go ahead with the same & do the needful.
I felt that pankaj suryavanshi purposely tried to make me loose my tamper by such behavior.
Sir / madam, i want to inform you that since 2 months i am job less and trying to work as free lancer and gather some cash to run my house expenses and other expenses. Same time i am in process of arranging funds from friends.
I request you to please take action against pankaj suryavanshi - i do not know whether this kind of exchange of words are really allowed to do with customers!!!
This is really shocking for me as for the very first time i got this kind of reaction / call from hdfc bank credit card dept. The office from where he called me was from kanjur marg.
I look forward for your intervention in said matter and hope to receive justice. As there is no personal revenge towards pankaj suryavanshi but really offended with his words used which was "threat" to me.

Thanking you.
