Airtel — about not fulfilling the offer given by airtel

I have recharged my account after seeing this given by airtel on 15june2018-rs99 mein unlimited local std aur roaming call saath hi 100 sms/din aur 1gb/din data+1gb data 28 din ke liye. Shartein laagu. According to which i should get 29gb data total but they have given me only 2gb data. I am fully elgillible for getting my full data to be fulfilled. I have complsined to customer care and their website but no response came. What does it shows that we the customers are fools as it is directly proved by their behaviour and i think they understood us the rural indian as in the case which was before. It also shows that the persons who do not know this much to complain about them what will they do think as it is your country also. Thank you.
