Vodafone Idea Limited — misuse of my email address

Dear sir,

I have been receiving emails from vodafone idea limited about pending payment for the following number registered on my name. This number is registered in mumbai where as i am from a different state. I have sent number of emails to customer service and the accountable personnel about this issue but all in vain. They keep sending me emails on pending payment.

I am worried if my details are being misused by vodafone and suspect it might be even used for any illegal activities or any not in favor of our nation. Just wanted to report it or if you could kindly please let me know to whom i can raise this issue would appreciate it. The mobile number is [protected] for which i being asked for pending payment.

Best regards
Brijesh
