HDFC Bank Bank Credit Card Division — asking amount around rs. 2, 35, 000/- for debited around rs. 1, 46, 000/-

Address: Chennai, Tamil Nadu, 600053

Details i had debited around rs. 1, 46, 000/-, i had already paid min. Amount due for 14 months around rs. 100000/-. But still i requested to go thru' the court and every day their collection agent coming with a person threatening about more payment you need to pay. Next more attempts stopping and if i speak every half day salary i need to lose for their discussions.
Their intention i should revert back the notice send to them and making pressure every day. I am helpless. I am unable to pay for them. Around 135700 rs asked me to pay in single shot on 28.07.2017. Which i need to get justice thru' the court.
