amount deducted

Location/place: banglore

Name of company/service: aircel ,internet package

I recharged my Aircel number wit internet pack of 98rs/- validity of 30 days !!! (That was displayed on the Aircel.com website ., but in real it gives only 28days!!!,maybe that is the way they cheat by deducting customer’s amount )
The internet pack lasted for 28days and my balance of 80rs got deducted for browsing internet . In between I was unaware of the validity and that is completely their fault ..
