I have recently changed my Vodafone operater to airtel operator. Airtel operater is much more expensive than its competitors operators. As well as airtel network is becoming a nightmare for the people anytime it goes and come. We never get what airtel has promised. Airtel make their customers fool and charge money for everything. Also customer care of airtel is really worst u . Call rate of airtel is much higher than other operators. They r doing nothing but making the money by fooling their customers.
