Airtel is one of the first largest mobile service provider in India. But their service is not good.They are simply charging on data usage and not getting correct usage information every time.I was using their 4G service from Dec 2015.first two months got correct usage data.This month I have recharged for 247 for 4G- 1 GB data /month.Recharged on 4th march, still I am waiting their confirmation message.
But, in between I decided to check whether it is updated or not so I just browsed some pages and checked balance amount but no changes.Let me tell you the interesting thing, data pack was updated in mobile.I lost around 6 days of not using the service!
