Received Suspicious Call From India (+91) Number, Requesting Block and Security Check

On September 19, 2025, at 15:28, I received a voice chat call from a number starting with the code +91 (India). I have no connection, friendship, or prior interaction with this person. As soon as I noticed the call, I blocked the number immediately.

So far, I have not observed any suspicious activity or issues on my phone. However, I am still worried about potential risks related to this incident.

I request that similar numbers be blocked automatically in the future, and that an official investigation be conducted in case there are any unauthorized actions on my line or account.

For reference, the last 4 digits of my customer number are: 3901. I will also attach a screenshot of the call to support my complaint.

Thank you for your attention, and I expect this issue to be resolved promptly.
