I'm Existing customer of SBI card as of now my financial condition is not so good and i m unable to pay the card payment on time whenever i have i have already deposit some amount around 60K in my card but from last 6 month i m unable to pay the payment.
SBI Agent call me and harassed me for payment and all one of the Agent is MR. Rajiv Thakur call me and told me that if you not pay the money i will file your case to legal and i will take up your parents from home and do whatever you want.

It's Totally unacceptable this kind of behaviour and all now in last 2 day i again receive the call from prachi Gupta she told me that how can you not pay the money i'm also going to take legal action and doing miss behave with me or his manager also.
