Airtel — Broadband disconnection 1

Hi, I have filed disconnection request of my broadband connection by airtel in the 3rd or 4th week of October since I got a connection from another internet service provider. I am receiving SMS and email stating I owe Airtel a huge sum of approx Rs.1500/- till date with is a major distress every other day and I am at loss of my mental peace, please help!

I'm in desperate need of help to get rid of you guys and it feels like clutch I'm stuck in with no help as any number of attempts to havey issue addresses are deliberately disconnected and nobody is heloing me till date. I request you to relieve of this distress, please!!
