Dear Sir,

I am using Airtel DTH Connection from July 2021, my Airtel connection number is[protected], i have shifted my residence now, and i want to refund my security back from airtel. but Airtel is denied to refund my security, they are saying that you have not recharge your plan with proper amount, so we cant refund your security, i have deposit Rs. 1500 at the time of connection and that time the said me that when you disconnect your connection we will refund your security, now ther are denied,

please do the needful.
