Dear...

I am using airtel no [protected] since long time back. Buy internet speed is very slow even i can not surf whats app and facebook properly.

I lodge a complaint against it but problem yet not solved. The are claim that airtel is a indias fastest network we are shown daily commercials on tv.
But we are facing problem everyday with internet speed, call drop and busy rought.
