A lady asked me if she could use my phone to make a call. I agreed and gave her my phone, while I was busy as a person from MGVCL were visiting, she made a call to a service(1800121170170) and took an otp. At first I couldn't find the message and I found that suspicious as it was hidden. Later I checked on cyber crime website and saw numerous crimes happening the same way that is why I am reporting this.
