I got scammed on phone call , please help me I am not sure what to do else I might lose money.

Hi, I need some advice regarding a potential scam my mom encountered today. Here's what happened: 1. My mom received a call from an unknown number. The caller, an elderly-sounding man, claimed to be from LIC and mentioned my father’s name, saying he needed to deposit money related to a policy. 2. The caller asked if this was the number linked to her net banking, and my mom, being innocent, confirmed it. 3. The caller claimed to transfer ₹50 first and then ₹500, ₹10,000, and ₹30,000, which he asked her to confirm. 4. After this, he fumbled and said he accidentally sent ₹35,000 instead of ₹15,000 and requested my mom to return the extra money. 5. At this point, I overheard and asked my mom to cut the call immediately, as I suspected a scam. Thankfully, my mom didn’t transfer any money back, but I’m worried about the safety of the account, as the caller knows the phone number linked to it. I haven’t checked the bank app yet because I’m paranoid that it might already be compromised if they’re monitoring the device. Questions: 1. How can I verify if any real money was transferred without risking account safety? 2. What steps can I take to ensure the account and personal data remain secure? 3. Should I report this incident somewhere? If so, where? Additional Details: I’ve already blocked the number and haven’t taken further action yet. Today is a bank holiday, so I can’t visit the branch until tomorrow. No OTP, PIN, or sensitive information was shared by us. Any insights or suggestions would be greatly appreciated! Thanks in advance. TL;DR: My mom (innocently) received a call from someone claiming to be from LIC, who pretended to deposit money into her account and then asked her to transfer back the “extra” money. We didn’t send any money, but I’m paranoid about account safety since he knows her net banking-linked number. What steps can I take to secure the account and verify if money was actually transferred without compromising our safety?
