SBI — Sbi credit card

Hello,
This morning I got a call from number +[protected]. I told to pay the amount in full. The officer told pay the step by step. I paid but my bank server was down at that time and I couldn’t pay at the moment. He talked to me rude and comment on my mother and wife. I told him my bank server is down but then too he didn’t listen to me. He downloaded my wife photos from the internet and try to make a comment on it and told me to put the photos on the porn site.
So what should I do now. I need a written statement from SBI that he will not misuse the photos then only I will make the payment
I have all the recording and snapshot of it
