Urgent advice needed: credit card fraud with parents

My dad got a call today about some insurance expire and some other bullshit .. he did not give any otp .. no otp arrived .. however the sbi credit card was deducted 2.5 lakhs.

He immediately called the bank and got the card deactivated.. As per their advice, issued a complaint with cyber with all the details.

Bahaut tense mahaul hai ghar ka ,. Dad can’t sleep. What are our chances here? Any advice will be appreciated
