Tata Indicom — Unnecessary Phone Calls

A company named 'Appu Hardware' seems to have given my Airtel Phone Number '[protected]' as their contact, and their Telecom bill seems unpaid with Tata Indicom. Tata Indicom folks has been calling me for bill payment frequently, and the frequency has only increased after I complained to them.

Have got around 50+ calls already and it comes from various numbers. Latest has been from '[protected]'.

I would not bother to get any compensation, but would like to Tata Indicom to immediately verify the phone number and stop calling me. Please help me here.
