Bharti Airtel — Deduction from main balance

Address:

Kolkata, West Bengal

I would like to inform you that I had recharged my mobile no-[protected] with Rs.153/-as a data pack with 500 MB valid for 21 days on 15/08/2015, but an additional 500 MB will be added later and also the validity will extend from 21 days to 28 days.But on 18/08/2015, I found that my main balance has gone down to Rs 4/- from 180/-.I called up the customer care executive but unfortunately I have not received any positive reply from their end. My question here arises that I have not received another 500MB.How is it possible to believe that I have used 1 GB with in two and a half working days. So my earnest request is to please provide my extra 500MB or my initial main A/C balance, from your end. Hoping for a positive response . Regards, Payal Sanyal(Naskar)
