Airtel — closing the the landline connection of airtel

Address:

Thane, Maharashtra, 4006044

We are from eternity commercial premises co. Op. Soc. Ltd. Teen hath naka
L. B. S. Road thane west maharashtra - 400604
And we have one connection of landline with air tel. But beside providing all information we didn't get bills and any notification about disconnection. Every time we have to call the customer care and asked for bill after disconnection. First thing not getting bill on time. Second thing not getting any information on registered mobile no. And another thing every time we had the same issue from so many days and no. One is considering the issue. So we want to disconnect the airtel connection.
