Dear @MohamedFahim
If you are facing a problem regarding the data service issue you are experiencing and have already lodged complaints to the Airtel customer service team, then you should approach the higher authorities.
This can be an error with the activation of your 2GB data pack.
In this case, we recommend you escalate this issue to the Nodal Authority of Airtel in your state. You can reach them via phone number or email.
To get contact details of the Appellate Authority, visit here: Contact Airtel Nodal Authority
Further, you may file an informal consumer complaint with the National Consumer Helpline (NCH) .
