Airtel — 149 recharge gave me wrong benefits - cheating done by airtel

It is showing under 'best offers for you' section of my airtel app, that rs 149 recharge would provide following benefits:
1) unlimited local/std/roaming calls
2) 1gb/day
For 28 days.

But after doing the recharge i received message saying :
1) unlimited local /std airtel calls
3) 300 mb data
My no is : [protected]
Circle: west bengal

How can airtel give false information? Rectify it at the earliest.
