I have used the airtel services from last 5 years. Airtel is most disgusting service provider in india, the network coverge problem is the biggest of this company, when you are outside of any buliding coverage is good but in you are going to inside buliding there is no network its just emergeny calls only.
and about the customer serviess is ok but not good, they is not provides the whole solution of ur query. they will say
or give another day to solve the issue or after daays they are not provides us the ultimate soln on any, just let it be
charges of pack is more than any other providers in prepaid and postpaid also gives numbers of taxes.
