Fraud with fake mobile number and fake email Id

Location/place: New Delhi

Name of company/service: Olx India

Hello sir, mam,
i want to inform u that some people are doing fraud by the name of olx india. Though no any con num is given on the website, it is difficult to check, who is right and who is fraud. They asked for some money to be deposited in the bank on the name of Preeti Sharma. We have lost some amount. But i would like to prevent others from this fraud. Fraud number is 8672080302
