Airtel — recharge refund denied

A recharge was done on my mobile for 5000, which was supposed to have been transferred to my paytm account, i spoke to airtel customer care ref no:cbnrv[protected], all they said is they can not help me and that i have to use the 5000 for their services only. This is outrageous, especially since they have no way of resolving the issue, i really hope someone takes notice and finds a way to help me.
