Airtel — airtel safe custody maintenance

Hi team,

I tried to maintain my airtel broadband connection in safe custody mode from past 5months. But airtel customer care is not responding. Instead, they are generating bill every month perfectly and taking my salary. I already raised an issue to customer care, which they were unable to process unfortunately. Now all of sudden, my airtel account number is showing as incorrect. Dont know still what miracles are going to happen. My humble request to disconnect airtel broadband connection permanently, so that i won't opt for airtel in my life..

Regards
Airtel customer.
