Hi Nagoorthamby,
Thank you for reporting this here in the Community. I would like to let you know that sharing contact information before a contract has started is against Upwork's Terms of Service and that all communications prior to the contract starting must take place on Upwork.
I've checked and was able to see the job you're referring to and the communications you had with the client in your Messages. I've shared your report with the appropriate team for further review. Our Trust & Safety team will surely look into this and take action accordingly if necessary.
We also encourage you to let us know if you find anything suspicious has happened by using the Flag as Inappropriate option throughout the platform. You can learn more about user reporting here. You may want to check this help article and this thread for more information on how to stay safe on Upwork.
