Tata AIG Insurance — Payment For Closed Policies

The guy with the mobile no. +[protected]. revealed to me my policy no which was prematurely closed and asked why i had to close it... He was claiming to be Mohit Agrwal from the jeevan beehma. The guy was persistent. He kept calling me frequently, i dont know why the company(most prob. their employee, in which case the client information, especially mobile no., should be accessible only to the direct agent or higher executives) selling their clients data to the likes. And unfortunately, again a lady have started calling me, Her No. [protected]. And I think the only thing I can do to evade is to Change My Phone No. I think these miscreant have made a professional network/organization, training exclusively on : How To Steal.
