So? Who gives an apology to a company offering service. The guy offended no one. It's a consumer-company relationship for god sake. Strange are people these days.

Yes to a certain extent it was his fault. Personally I never receive the bills too and have to check online. However the guy has reason to complain if he didn't receive the computerised warning too.
I have had experiences with Airtel Mobile, oh god...what can I say even after paying all dues and CLEARLY asking them to disconnect the connection...I continued receiving the bills and quite rude phone calls from their employees. Thank god I had written records of each bill as well as the document showing the proof I had asked for disconnection, otherwise those morons would have charged bills even after disconnection.
They gave no apology to me for that.
I say to everyone to cheat Airtel Mobile and run away with undue bills, if they can. Airtel deserves it. :angry:
