Hi all, I am getting message from this number, 08884659209.

Dear Customer, Your website & email will STOP suddenly, if you do not renew your domain name & hosting service. For Support 8884659209.

When I called they told this is netcom company in bangalore, yes we have messaged you, but when I asked them from where you got my domain details, they put down my call and after calling, they are not receiving my calls. How they got my domain details and why they are calling for the renewal, as I am the registrant and I have all the rights to renew it.
