Airtel
No signal and busy customer care lines

My Airtel sim card stopped showing any signal all of a sudden this evening and since then there is NO COVERAGE. I have no idea of hat to do, all my matters at work are suffering due to this inconvenience. The customer care kept me hanging for long making me wait for the executive and soon the lines got busy. Now i have no clue of what to do. I am seriously in great problem. Please HELP.
