Max Bupa — sharing of client details to 3rd party

Address:	New Delhi, Delhi
Website:	Max Bupa.com

I have a health insurance with max bupa and the agent name is ravi arora.
But the agent and company share my contact details to some 3rd party and they are calling me and sending emails to buy new policy and renewal of my old policy.
When i asked the agent about this, he said he gives my details to some other members who can do the follow up with me... He is so careless in his attitude regards to customer data secrecy. He also mentioned that i am working like this for past 10 years and i have never seen any rule for this customer data secrecy.
I raised the issue with max bupa and they didn't provide any resolution.
Customer data secrecy is not maintained by the company nor by their agent.
Request to take strict action.
