Unknown Person — getting continuous calls

Dear sir/madam,

I am getting continuous calls from unknown person with mobile no : [protected]. I thought it might be fradulent call to get banking details, otp's or aadhar details etc. I have got today dated 29/04/19 at 19.29pm. Please take action on this mobile no. It might be mobile number from rajastan. I have already blocked from my side, but to avoid fradulent activities from this mobile number, i am giving complaint. Please take it as serious and take severe action on this unknown person by tracing his mobile number.
