Airtel — incorrect information about 46rs promotion

Address:

Kolkata, West Bengal, 700029

Hi as per airtel advertisement its says that unlimited hellotunes at 46rs for 28 days so i recharged it this morning and tried to activate hellotune through airtel app but it was not going through. I called up 198 to complaint about it but the agent said to get full information i should have called customer service before doing a recharge as this is the service only to change songs at no extra cost therefore i informed agent that no such information is mention in airtel app nor in 121 service & neither its mentioned t&c applied so if this is the case then its a false advertisement made by airtel & to which initially the agent agreed to the point but refused to log a complaint when i insist to do so. Kindly look into the matter as i want to resolve it before taking it further and have also attached screenshot about the offer for your reference.
