Airtel — airtel steals my internet data at midnight

Address:

Hooghly, West Bengal, 712101

Dear sir/madam,
I previously used jio (Rs. 399 scheme) but there i faced some calling issue, i heared that airtel launched the same plan and also activated 149 scheme for 28 days (1gb/day =12 am to next 12 am+unlimited calls and 100 sms /day offer),. After that i recharged airtel for rs. 149. I saw 1 gb of my remaing data at 1 am, after that i slept. Next day morning at 8 am i saw my balance is 186 mb of 1 gb daily limit. I called customer care (121) but they told my they are unable to say when that data balance cut down. They tried to insist me that i consumed that 814 mb data after 1 am. So, airtel cheated me at the very first day of recharging. Jio never done thing. Infact in jio, data was valid till 12.30 am (30 min more that airtel).
