Cheating on Credit Cards after years

Location/place: Hyderabad

Name of company/service: standard chartered Credit Card

Hi All,

I have been cheated by standard chartered bank many times . I go to bank and asked many times what is my final amount and pay the the money but everytime they keep a 200/300 lest than actual amount which they disclose after years and force to pay an heavy amount for 15000rs and if you refuse they bargain they threaten you many ways and makes you pay atleast some thousand rupees. Please do something about these cheaters. if any one reading it dont take any credit cards from this bank EVER.

Early action appreciated.
