Airtel — Unable to recharge via Airtel Sim balance

Address:

KASARAGOD

I had submitted a request to Airtel customer care & they told me that there is no way to recharge via SIM balance.I have ₹6, 500/- in my Airtel sim balance.What shall I do with that money??I have simply invested my money to Airtel & i am unable to use my own money.Is this a fair reason given by Airtel customer care executive???

Please have this issue resolved & re-enable 'recharge via talktime balance' option again which was being used before, such that I can use my ₹6, 500/- which is left unused as Airtel sim balance.
