Airtel — Main balance of prepaid mobile

I had charged my prepaid mobile number [protected] with various amounts, from time to time about five years back, with the intention o[censored]sing my main balance amount for charging it with different plans (including increase in validity) as and when needed. My main balance is Rs 8, 404. Now, this facility has been suddenly withdrawn by your company, and I cannot use this amount of my money for recharging, as confirmed by your nodal officer. Consequently, the amount of Rs 8, 404 deposited by me with you is stuck and has become completely non-usable for me.

Therefore, please refund my money (Rs 8, 404) lying with you so that I can use it for recharging my mobile as payment for the purpose.

Thanks
