Airtel — recharged but become useless due to poor communication from the airtel

Outgoing and incoming was stopped since the plan expired on one of our family number being used by my nephew. So, I recharged with 48rs first but no incoming/outgoing and the auto message asked to recharge for unlimited plan so I recharged again with 19rs for 2days plan but still no change and again he auto message asked to recharge for unlimited plan. As my nephew had to travel a long way to his college had no choice to recharge again with 149rs for 28days unlimited plan. Even that didn't go our way still no incoming/outgoing.

So, I rang up to customer care and explained the situation and the necessity of having that number activated. One Mr. Ajmal took my call and conveyed me after going through the details that the incoming / outgoing was stopped because it was 3G sim and asked change to 4G sim only then it will work(this sim is being in use for more than decade now was just few day after its plan expired). To my surprise this information was not communicated to me at first place instead over the call auto voice message misled me to recharge for unlimited plans to activate the incoming / outgoing.

The irony is that the customer care representative went on to say that you have a 4G handset and your sim is 3G so we have blocked the incoming / outgoing. Either you have your sim to 4G or you put your 3G sim in 3g mobile. That was ridiculous. I said that you are giving the information of late and we are in need of this number as my nephew is travelling overnight and alone. It will worry us if he dont have a number to communicate then and there.

But Ajmal was very stubborn and gave us no choice except to change the sim or phone. It was around 8PM that this call was made.

I need expert in this matter or senior members advise to take the issue further to get the telecom operator to respond sensibly and refund my amounts which went worthless due to ignorance of airtel.
