I have had the misfortune of trying to upgrade for a 3 monthly mega pack which they are not doing and deducting rs 13 on a daily basis. they have the audacity to ask me to put in the difference (since they have been merrily deducting rs 13 everyday for last 4 days) and only then they will upgrade my package. Government asks us to digitize.
let them try airtel digital and they will definitely revoke their decision.
