Airtel — false number linked to my email address

Address:

Pune, Maharashtra, 411045

Airtel is sending the mobile bill of [protected], to my mail address and also calling me to pay the bills, this is not my number not even belongs to any of my relative.

I suggested airtel many times to correct the data at their end or call the customer directly. Or cut down the connection user or customer will contact them back.

But every time airtel giving assurance to correct the data at their end. (I have proof as written emails from airtel side). But it is not working so writing here.
