Airtel — billing and network issue with airtel

Address:

140603

I am calling airtel cust care since 20 days regarding my bill issue but no resolution till now. Airtel already barred my services for not paying outstanding bill in just 7 days of generating bill. Today some cce put me on hold for 20 mins & didn't turned up.
Airtel is india's excellent network... Only in making excellent ads but nothing else...
Wo kya ad hai? Ye ad vad choro aur apna network...
