Airtel — 1gb data for rs 49 not credited to my data plan

Address:	Mumbai City, Maharashtra
Website:	airtel.com

Tonight i went over my daily limit of 2gb per day per my data pack, and i exhausted all of my calling plan money. So i added rs 500 to my calling plan at the mobile store and then added 1gb of data for rs 49 via my phone.

My calling plan balance went down to rs 451, and i received a confirmation that 1gb of data had been added to my data, but when i checked the balance i still had 1mb of data.

Then, i added 115mb of data for rs 29. Again, my calling plan amount went down (Now it is at rs 422) but this time the data was added to my plan and that is what i am using to submit this complaint.

Where is the 1gb of data?
