State Bank Of India [SBI] — sbi debit card fraud

I had received a call in my mobile number from phone no.91-[protected] at 11.30am from a person named arun kumar who is introduced as working in reserve bank. He asked me to tell the renewed sbi debit card no., expiry date and cvv no. For updating the gst records. He is aware of my old debit card no. And asked for the renewed card details. I told him that these particulars are not to be told through phone. On hearing this, he stated that if the details are not told the whole money in the account will be debited. I did not told him the cvv details and he threatened to close my accounts. I closed the call and again and again he called, but i didnt take the call. You are requested to take suitable action against the above telephone connected person at the earliest. I have blocked my card after this incident.
