When I see a Advertisement of airtel that it is india’s largest network that provide as per there promised but it is nnot Truth What they say not give to it’s costumer.Airtel is worst services that I seen.airtel iis worst due to most point is it’s charges and billling.I recharged of it’s monthly plan and they not give full validity according to plan They cut 30 days validity.When I call costumer care then they say we give according to plan check plan in our websites and then call.when I check it’s website about plan then we will see that the show two plan at same price.This is the first Reason why the airtel is worst.second is their network is not stable and internet speed is medium.So I don’t recommend Airtel the india’s Largest Network.
